Summary:
We have made great efforts and accumulated experience in exploring the magnetic structure and dynamics in the chromosphere in the past several years. By comparing the Stokes profiles between chromospheric and photospheric spectral lines and with Stokes asymmetry analysis, we have found significant differences between the two layers for various regions. These differences hint at dramatic changes of the field inclination, strength, and plasma flows from the photosphere to the chromosphere. We are collaborating with researchers in Max Planck Institute for Solar System Research (MPS, Germany), Big Bear Solar Observatory (BBSO), and University of California Riverside for chromospheric Stokes inversions, more chromospheric observations, and non-force free field extrapolations, respectively. These prepare us for exploiting the unprecedented imaging chromospheric Stokes data that can be provided by the newly launched Hinode (Solar-B) mission. We propose to make further efforts to study the accurate magnetic field and plasma flows in the chromosphere, as well as their connection with the photosphere and their role in the coronal models, with Hinode Spectro-Polarimeter (SP) and Narrowband Filter Imager (NFI) observations and our well established experience and techniques. We arrange our proposed project in the following three connected tactic steps:Performance Year | Reference | Actions |
