Poynting Flux and Joule Heating in the ionosphere – latest results from the challenge and updates at the CCMC. With the addition of satellite tracking and display features in the online analysis tool and at the Community Coordinated Modeling Center (CCMC), we are now able to obtain Poynting flux and Joule heating values from a wide variety of ionospheric models. In addition to Poynting fluxes derived from electric and magnetic field measurements from the Defense Meteorological Satellite Program (DMSP) satellites for a recent modeling challenge, we can now use a Poynting Flux model derived from FAST satellite observations for comparison. Poynting Fluxes are also correlated using Ovation Prime maps of precipitation patterns during the same time periods to assess how “typical” the events in the challenge are.
