DMSP Comparisons with Ionospheric Electrodynamic Patterns

Integrating ionospheric electrodynamics with upper atmospheric models requires systematic validation against observations. This study supports the objectives of NASA’s Space Weather Operational Readiness Development (SWORD) initiative by comparing outputs from a wide variety of ionospheric electrodynamics models with measurements from the Defense Meteorological Satellite Program (DMSP) satellites. Models include Weimer, SWMF, MAGE, Super DARN, FTA, Ovation, etc. These models provide estimates of high latitude electric potential and auroral precipitation parameters (mean energy and energy flux), ion drifts, etc. We conduct comparisons of model outputs with DMSP observations across a variety of geomagnetic storm events and model configurations. Preliminary results from these comparisons will be presented, with an emphasis on identifying strengths and limitations relevant to future modeling efforts.
