Summary:

This proposed work will use existing multi-year satellite observations of ionospheric density, middle and upper atmosphere temperatures and a 3D nonlinear general circulation model to address the following outstanding science questions:



1. What are the relative inter-annual and solar cycle effects on the mid- and low-latitude ionosphere?

2. How far do solar rotational effects penetrate in the mid- and low-latitude ionosphere?

3. What are the quantitative effects of flares on ionospheric heating?
