83April 26, 2016This is very important. The largest storms contain the most heavy particles outflowing from the ionosphere to dominate the magnetosphere and until we have measurements and models that effectively include ion composition these rare and most dangerous space weather events cannot be understood to the point of predictability.

IDComment DateComment
94April 28, 2016Further investigation into the inter-hemispherical differences in conductivity is very important and far reaching in terms of terrestrial- and space-weather modeling and forecasting. I would suggest to call the ionosphere a region, rather than a boundary, though it can be represented as such in a numerical modeling framework. I would also strongly encourage studies that use existing ground- and space-based remote sensing and/or in situ techniques, which could be combined, either directly through data-assimilation or used for validation, with theoretical and modeling efforts.
68April 26, 2016I think the time is ripe to do some more quantitative work here, as suggested. Our understanding of this has so far been mostly qualitative.

IDComment DateComment
73April 26, 2016This subject is certainly overdue. The SEP community cannot ignore the magnetic connectivity issue anymore. While imaging data can be used to constrain the location of a shock (e.g., SDO, STEREO, etc.), but ultimately the magnetic connectivity issue can only really be addressed with the MHD models. The topic is timely because it can help figure out the magnetic connectivity of Solar Probe and Solar Orbiter in the future.

IDComment DateComment
79April 26, 2016This is a very important and challenging topic. We need answers to several questions which are critical for understanding the solar wind – M-IT connection. How much energy is being transferred into the IT system from the magnetosphere and the solar wind? How well can we model the IT energy budget during geomagnetic storms and quiet times? What are the major forms and locations for energy inputs into IT? Can we use direct observations to derive energy proxies? These questions also need to be addressed to advance forecasting of IT dynamics in geomagnetic storms.
64April 26, 2016Agree that this topic is important and timely. In order to properly address the influence of magnetospheric energy and ionospheric feedback, ion outflow and the resulting changes to magnetospheric composition should be addressed.

Timelines of proposed topic is determined by coordination between many last missions recently became available that gives possibility to conduct even more deep studies.

91April 27, 2016This is an important topic, as active region coronal fields represent the ultimate source of all space weather phenomena. At the same time as NASA's system observatory (SDO, Hinode, IRIS, STEREO) is providing imagery and spectra of such dynamics, advanced models of the solar coronal field are now coming online (much as a result of an earlier LWS opportunity: NNH11ZDA001N-LWSCSW). As a result, the time seems right to sponsor directed research that makes use of both observational and theoretical advances, and this topic has the potential to do that.

IDComment DateComment
62April 26, 2016This topic is crucial to the goals of LWS, as it drives or influences all forms of solar and geomagnetic activity. While MMS provides unprecendented views of small-scale reconnection processes, the coupling between large- and small-scale processes is a crucial knowledge gap that MMS alone cannot address. Theory, modeling, and observations that address this coupling will be necessary to address the question of reconnection onset.
50April 25, 2016The topic is timely and relevant because the missing physics of magnetic reconnection onset is one of the major stumbling blocks in heliophysics models, including those of the Earth’s magnetosphere, solar wind and corona. Existing models rely on numerical or explicit ad hoc resistivity and oversimplified current sheet geometry with antiparallel field lines, which are very different from realistic pre-onset configurations. At the same time, the present multi-probe missions as well as laboratory experiments, which already reached the collisionless regime, offer a wealth of data and give a promise to the closure on the problem, which will strongly boost our understanding of the heliosphere and its predictive capabilities.
46April 25, 2016Magnetic reconnection onset is usually believed to be controlled by electron kinetics. With MMS launched the timeliness is perfect for this research. Particle in cell simulations can provide a model and theory to describe reconnection onet.

IDComment DateComment
92April 27, 2016I disagree with the above commenter who states that we should not expect any progress. In fact, progress is already being made, especially as the LWS program has sponsored programs that make use of both observational and numerical modeling capabilities. I would argue that the previously sponsored programs have been at the heart of what LWS is about, and the proposed topic here is in this same vein and thus seems likely to lead to further progress.
76April 26, 2016I don't understand why we should any progress after all these years of observations.
April 25, 2016Auroral Morphology: the result of magnetosphere input and the origin of atmospheric-ionospheric-magnetospheric processesSSA-1, SSA-2, SSA-4, SSA-5Comments 5
IDComment DateComment
90April 26, 2016The ground-based auroral observations has been used widely in support of many NASA missions and scientific objectives. It is an essential tool for validating the results from the models and space-based in-situ measurements. To investigate the auroral morphology and maximize the science return, the ground-based observations should and need to be included as an integral part of LWS solutions.
80April 26, 2016It may be worth to mention the importance of the meso- and small-scale structures in the aurora to the upper atmosphere.
71April 26, 2016The interaction between the hot ring current ions and cold plasmasphere ions leads to so called ring current aurora (RCA). RCA typically locate at sub-auroral latitude and can spread to the entire ionosphere and thermosphere due to charge exchange. Observations of RCA provide a way to remote sensing of the ring current and plasmasphere structures. Structures in the auroral oval also affect the accuracy in Joule heating estimation and impact ITM simulation and forecast.
55April 26, 2016One drawback to progress on this topic is the uncertainty in magnetic-field mapping between active aurora and the magnetosphere: this prevents the connection of critical magnetospheric measurements to the auroral forms.
45April 25, 2016While the topic of Auroral Morphology alone is a narrow topic, the concept of studying the auroral processes as a gateway between the magnetosphere, ionosphere, and atmosphere is compelling. Examining these processes for linear and non-linear effects; collaborating between magnetosphere, ionosphere, and atmosphere scientists with expertise in modeling, data, theory, and data assimilation. This topic can actually be constructed as a board topic, where wave generation of discrete aurora can be examined in context of the resulting gravitational waves and transient ionospheric disturbances. The concept should be considered as a meeting ground for many disciplines with the goal being to provide a method for modeling the auroral morphology in a way that allows other topics to use it as input.

51April 25, 2016If "The impact is also noted in the ionosphere and atmosphere", this will even more important and interesting.
41April 25, 2016Agree on the timeliness and importance of this topic. The impact is also noted in the ionosphere and atmosphere.
40April 25, 2016Most substorm-related phenomena have indeed been statistically observed to be prevalent in the premidnight sector. It is high time we understood WHY that is the case. This question is very timely--we can keep on collecting more statistics that show the dawn-dusk asymmetry, but that isn't explaining why it happens. That is the next step. The Heliospheric/Geospace System Observatory will be well-positioned to help answer that question, with THEMIS and MMS 180 degrees offset from each other, and many other missions filling in the space in between.

49April 25, 2016The topic is important and timeliness is great. However, for a better description of these transients, kinetic simulation models in global setups are needed, such as global hybrid and coupled MHD-PIC ...
47April 25, 2016This topic uses the potential of the multi-probe missions Cluster, THEMIS, and especially the present conjunction between MMS and LWS Van Allen Probes missions, to address one of the most compelling questions of the inner workings of the magnetosphere. The mechanisms coupling magnetic reconnection processes in the magnetotail and at the magnetopause to particle injections in the inner magnetosphere represent a critical missing element in the global magnetospheric models. Their understanding and implementation into the present models is key to the next major leap in the space weather prediction capability development.
37April 25, 2016This topic is particularly timely in that there have been many advances recently that can locate reconnection throughout the magnetosphere in global simulations, therefore making the larger question of reconnection's penetration that much more achievable. Additionally, this topic addresses the open question of how to address reconnection's role as the source population for the inner magnetosphere; not much is known how reconnected particle distributions change as they travel from the reconnection site in the distant magnetotail (~20 Re) to the inner magnetosphere (~6 Re). Furthermore, this topic could address the need for improving modeling approaches which couple global MHD and kinetic inner magnetosphere models since MHD ***cannot*** properly address the relativistic flow boundary between these two regions.
April 23, 2016Topic Title Geoeffectiveness of Upstream Variability and TransientsSSA-0, SSA-1, SSA-6Comments 10
IDComment DateComment
88April 26, 2016Understanding when, where, and how significantly foreshock transients modify the solar wind just prior to its interaction with the Earth’s magnetosphere is important to comprehending solar wind-magnetosphere coupling as well as individual magnetosphere and ionosphere reactions to driving forces.
86April 26, 2016I would like to point it out that these transient phenomena are frequently observed and they could be an important source of ULF waves in the Earth’s magnetosphere, some of which can play an important role in the dynamics of Earth’s radiation belts. The ULF waves generated by transient phenomena near the bow shock in both Pc3 and Pc5 ranges have been reported.
85April 26, 2016I would like to point it out that these transient phenomena are frequently observed near the bow shock and they could be an important source of ULF waves in the Earth’s magnetosphere, some of which can play an important role in the dynamics of Earth’s radiation belts. The ULF waves generated by transient phenomena near the bow shock in both Pc3 and Pc5 ranges have been reported.
74April 26, 2016Spacecraft observations and global kinetic models have, in the past decade, demonstrated the significant role of the upstream waves and transients in magnetospheric dynamics. However, much remains to be learned about the physics and impacts of upstream phenomena on the magnetosphere. The proposed topic is very timely and the planned studies and approaches are well thought out.
72April 26, 2016We still have much to learn about how exactly do the upstream phenomena modify the bow shock, what are their signatures in the magnetosheath and in the magnetosphere. These signatures should be studied with much care and their impacts should be evaluated.
54April 26, 2016This a rapidly developing and clearly important topic. The community has to sort out all of these new phenomena, sooner being better than later.
39April 25, 2016The increasing availability of spacecraft observations from multiple constellations and increasing coordination between satellites and dense networks of ground-based observatories (e.g., SuperDARN radars, ground magnetometers) make this a very timely topic. There is mounting evidence that these fluctuations can affect space weather, and these are the right tools to better characterize their role.
36April 25, 2016The transients identified here ultimately play important roles in the generation of magnetospheric waves which can control the rate of reconnection both at the dayside and in the magnetotail, while also generating different waves throughout the magnetosphere. This topic highlights the need for improving magnetospheric models for forecasting purposes by utilizing current spacecraft observations. This topic is timely to address longstanding problems with magnetospheric space weather forecasts.
35April 25, 2016Actually the increase in dynamic pressure can often be several hundred percent. I am wondering if we are beginning to se a similar paradigm shift as that of BBFs vs laminar flow in the magnetosphere, but now behind the quasi-parallel shock.
33April 24, 2016I'd like to point out that these foreshock-generated fluctuations are by no means minor. They typically introduce ~100% variations into the pressure applied to the dayside magnetosphere, either as quasi-periodic waves or step function changes. Further, they drive large amplitude localized currents and particle precipitation into the high-latitude dayside ionosphere. They may account for a substantial amount of the (magnetopause, magnetosphere, high-latitude ionosphere) variabilty that cannot be predicted from L1 monitors.
April 22, 2016Geoeffective storms and the solar wind features which drive themSSA-0, SSA-1Comments 3
IDComment DateComment
63April 26, 2016During the extended solar minimum there were "geoeffective" storms wherein the Dst did not reach -100. In the ionosphere and neutral atmosphere the true measure of effectiveness is whether it alters the neutral or ionized environment and those storms were quite effective in terms of changing the character of the thermosphere in ways that the models were not able to reproduce. This "geoeffectiveness" was, at least, partly enabled by the lower density in the thermosphere due to the lower solar output which led to a lower exospheric temperature.
53April 26, 2016Discerning the different storm phenomena from their solar wind drivers is a new and growing topic. Preconditioning of the magnetosphere by the solar wind preceding the storm driver is not fully understood. Mach number effects, density effects, and the effects of solar wind fluctuations have not been sorted out.
32April 22, 2016This topic is ambitious in attempting to combine data products from the entire heliosphere to more fully understand the causal chain from solar surface to the response of Earth's atmosphere. This is not a criticism, but rather makes the entire topic wholly appropriate for LWS' scope in forming large collaborative teams of experts from areas which traditionally may not interact.

IDComment DateComment
98May 11, 2016Data assimilation has been instrumental for both scientific and predictive understanding of oceanic and atmospheric processes, and it is becoming very important area in space physics due to new observational datasets. Many lessons to be learned from the ongoing data assimilation efforts in climate and weather community. However, adopting existing new methods can not be blind. Efficient technology transfer is only possible by taking account some similarities of modeling these geofluids by first principles physics models, as well as by recognizing important differences due to predominantly external(in space physics) vs. internal (in weather/climate) origin of variability. There will be also need to develop new data assimilation methods for the space physics models that don’t have analogues on lower altitudes.
96May 2, 2016The ability to predict space weather is composed of not only a modeling effort, but also an effort on developing and implementing appropriate data assimilation methodologies. The space weather community is now starting to recognize this need and many have made advances towards this goal. It is important to note that space weather poses particular challenges, such as data sparsity and nonlinearities in models, that need to be address and for which new assimilation methodologies need to be developed. This effort will greatly enhance space weather predictability and produce improved model and understanding of physical phenomena of interest.
77April 26, 2016Promising approach. Need to try new thing to move field ahead.
67April 26, 2016I agree with the other comments. This is another area where targeted science can make major breakthroughs.
38April 25, 2016This is especially needed for the high latitude ionosphere-thermosphere-magnetosphere, where the data is relatively sparse for processes that vary on timescales lasting only minutes. The sparse data we have show an enormous variability that is not well spanned by current first principles models. To really understand what is happening we need DA.
24April 22, 2016This is a highly realizable topic which utilizes advances in computer resources and techniques. Terrestrial weather science incorporated ensemble forecasting to improve their predictions to somewhat reliable 1-day forecasts over the last few decades, space weather is similarly poised with our state-of-the-art computational models and output.
23April 21, 2016It is a great opportunity take advantage of the computational capacity improvement and new sources of solar wind data to add Data assimilation (DA) technique into geospace models. Such improvement can produce more realistic analysis of the ionosphere - thermosphere system.
April 19, 2016System-Level Physics of Geospace: Quantitative Analysis Using ImagingSSA-1, SSA-4, SSA-6Comments 6
IDComment DateComment
89April 26, 2016Although the space-based imaging is important for system-level study of geospace, the ground-based imaging capability can provide measurements to not only compliment the in-situ observations but also validate the results based on the in-situ measurements. It is important to include the ground-based imaging capability for quantitative analysis in this topic.
81April 26, 2016Soft X-ray imaging is a major omission in this topic description. Significant solar wind charge exchange (SWCX) emission that produces soft X-rays originates from the magnetosheath and deep within the magnetospheric cusps. Numerous papers have analyzed these emissions observed by astrophysical telescopes and recently-developed wide field-of-view imagers and modeled the emission. The signal is plenty strong to provide global imaging on a physically useful cadence.
61April 26, 2016Global imaging is absolutely necessary to provide global context for in-situ measurements, and also has the ability to measure and track the global magnetospheric response to external inputs. Further global imaging can potentially catch events such as K-H instabilities and FTEs which are much more difficult to find using in-situ measurements. To make significant progress it is probably necessary to provide global images on a fairly fast cadence (1-2 minutes). It has recently been shown that x-ray imaging can provide high-statistics global images on this cadence for a moderately sized instrument situated at the right vantage point. This technology should definitely be part of the discussion.
59April 26, 2016It is very timely to develop imaging techniques that quantify geomagnetic activities. IBEX, TWINS, IMAGE, etc have accumulated many images of the Earth’s magnetosphere and ionosphere. Two soft X-ray imaging spacecraft, SMILE and CuPID, plan to launch in 2021 and 2019, respectively. Science communities provides a wide pool of global simulations and in-situ observations that can validate the quantitative analysis derived from images. Therefore, I highly recommend this topic.
34April 25, 2016With the vast data base of previously obtained narrow field-of-view soft X-ray measurements of charge exchange emissions from the Earth's magnetosheath and cusps, the extensive modeling of these emissions now going on, ESA/CSA's selection of the wide field-of-view soft X-ray imager on the SMILE mission, and NASA HTIDes selection of the wide field-of-view soft X-ray imager on the CuPID cubesat, it is important to expand global imaging studies to include measurement techniques other than ESA and EUV. The techniques are in many ways complementary and needed to obtain the full picture.
26April 22, 2016This proposal is timely in addressing current gaps in observational data products. While much has been gleaned from simple 2D models, it is becoming increasingly apparent that the 3D structure of the magnetosphere and plasma environment have important effects on the global magnetospheric response.

IDComment DateComment
25April 22, 2016While interesting in scope, it is not sufficiently described what would be learned from Solar Cycle 24 to assist in Solar Cycle 25. Looking at the last few solar cycles, there has been a trend of alternating activity patterns between very high activity (21/23), and relatively milder activity (22), so it is unclear how an extensive study of Solar Cycle 24 would have 'important implications for Solar Cycle 25.'
19April 20, 2016Although the results of this research may help aid models and understanding of the boundary conditions and input into to the magnetosphere, ionosphere, and atmosphere I'm not sure how the proposed research topics address SSA1,2,3,4, or 5. Could the proposes address this? Perhaps this topic could be expanded to include potential research areas such as the affect of the weaker solar cycle on the occurrence of geomagnetic activity, particle loss to the upper atmosphere, and comparative work between more active solar cycle times and the current solar cycle.

93April 27, 2016The thermospheric conditions (density, temperature and composition) are mainly impacted by the competition between the heating and cooling processes. Much of effort focuses on improving the specification of the heating.

IDComment DateComment
21April 20, 2016Reliable solar wind and IMF data from an L1 monitor is critical to forecast many aspects of the sun's affect on the Earth, including how it affects the plasma environment inside our magnetosphere. An L5 monitor would also dramatically increase our predictive capabilities, as well as provide information as to how plasma and fields are modified as their solar source region evolves.
18April 20, 2016As L1 is the likely spot for long term solar wind monitoring I think that this is a very important topic. However, while we have STEREO, we should take advantage of this data set to validate what L1 is observing as well as improving current solar wind models.
April 15, 2016Neutral composition effects on the ionosphereSSA-4, SSA-5Comments 2
IDComment DateComment
70April 26, 2016The thermospheric condiitons control the ionosphere in a number of ways, such as the composition (O/N2 ratio) impact on ionospheric density and nitric oxide and CO2 cooling effect on ionospherc temperature. The thermospheric conditions may also impact the ionospheric ion up/out flow. Thermospheric neutral wind can redistribute the ionosphere through ion-neutral drag.
27April 22, 2016While this is an important topic worth pursuing, it is unclear what kind of studies would be pursued under such a targeted research. It is also stated that 'conclusive results can only be achieved with data from upcoming new missions (e.g. [GOLD] and COSMIC-2),' this gives me the impression that such science opportunities would be part of the prime science phases of these missions, and likely not applicable to LWS.

April 12, 2016Longitudinal Variability of Equatorial ElectrodynamicsSSA-2, SSA-4, SSA-5Comments 2
IDComment DateComment
66April 26, 2016This is a very important topic. There is much yet to be understood in longitude regions that are not well-instrumented.
48April 25, 2016This topic is timely because many satellite observations will be available. The title mentions equatorial region, but the region under the influence of the equatorial electrodynamics is about a quarter of the whole ionosphere. This is the region where the plasma density is the largest and most severe scintillation occur. The longitudinal variation in plasma density or irregularities is associated with plasma-neutral interaction, forcing from lower atmosphere, morphology of the geomagnetic field, and coupling of the E and F regions. The focused study of this topic by combining observations and model simulations will significantly improve our understanding of the complex physical processes in low latitudes.

31April 22, 2016Given that these extreme solar events occur so infrequently, and even less so directed at Earth, how would a targeted research of potential impacts on Earth assist in improving operational forecasts of Geospace? It is difficult to see the linkage between these events and improving near-Earth models as addressed in SSAs 1 and 6.

29April 22, 2016Advancing understanding in the area of wave-particle interactions in geospace will greatly improve forecasting capabilities of the current computational models. An area of focus could be quantifying the spatiotemporal distribution of different waves for a single event, although this may ultimately be limited by observations.
20April 20, 2016To properly understand our geospace, including the impacts and hazards to spacecraft and astronauts, it is critical that we advance the knowledge of how waves interact with particles. Additionally, this physical mechanism has scientific impacts outside of the near-Earth system.
17April 19, 2016Perhaps this topic could also include wave-wave interactions and the affect of lower frequency waves modulating higher frequency waves and the local particle population. Ground based instrumentation may also be able to help with answering these questions through observations of ULF waves as well as inferred electron precipitation to the upper atmosphere.

16April 19, 2016Can you explain how this topic related to magnetospheric variability, satellite drag, solar energetic particle events, the total electron content in the ionosphere and the radiation environment in the Earth's atmosphere?

97May 4, 2016This is a very important research area to be explored. It is definitely needed to take advantage of the recent big advancements in machine learning for the space weather research. This will help fully explore the science values embedded in the large solar and space data.
95April 28, 2016We should also encourage direct collaboration with experts/specialists in big data analysis from other fields as part of this effort. This would allow cross-disciplinary interaction and help to efficiently and effectively implement big data techniques in space physics research.
65April 26, 2016This is an important topic. So much new capability is available now and it could be a game-changer in our community.
42April 25, 2016Like. I agree with the other comment. This is definitely needed by our community.
28April 22, 2016Something like this desperately needed for Space Physics. Incoming data sets are simply too large to be analyzed by individual persons and therefore setting loose the power of armies of computers can increase forecasting capabilities exponentially.

15April 19, 2016It is not clear how this suggested topic addresses Geomagnetic Variability (SSA-1). The suggested topic may be of general heliophysics interest as its description does not describe how it is linked or addresses directly any LWS goals.

84April 26, 2016That's a nice topic. Author should consider to add that current prediction models limited accuracy in prediction of CME arrival time.
43April 25, 2016"magnetic" is misspelled in the title. A lot of us are also interested in what happens to the CME after it passes the Earth and reaches the outer planets.
