Upper Atmospheric Electrodynamics
We study the upper atmospheric electric field and plasma drifts using measurements from very large radars and several satellites. We have developed the most widely used empirical global ionospheric plasma drift and electric field models. The current topics of research focus are the response of the low latitude ionosphere to sudden stratospheric warming and geomagnetic storm. This work is in collaboration with research groups in Germany, Denmark, Brazil and Japan.
