Griffin, J. M., T. Connor, and H. E. Snell, “Upgraded Auroral Model for Inferring and Forecasting Globally the Precipitating Electron Dosing To Drive Space Weather-Based Models” presented at AMS 90th Annual Meeting – Seventh Symposium on Space Weather, Jan, 2010 (poster)

The Hardy-Gussenhoven Auroral Dosing Model (HGADM) provides the electron characteristic energy, energy flux, and number flux as a function of Kp, geomagnetic latitude and local time. We expanded the capabilities of the HGADM by allowing the use of Auroral Boundary Index (ABI) information, based on the DMSP SSJ particle measurements, to provide a means for correct geographic placement and dosage scaling of the auroral oval. By applying techniques to project future values of the ABI, the HGADM may be run in a forecast mode and, when coupled with a suitable space weather-related model, allows for the prediction of expected modeled responses on a global basis and to be used in determine conditions along a given sensor line-of-sight. In this talk we present a working example of how our expanded HGADM can be used for determining the integrated line-of-sight optical radiance as observed by space-based sensors, and present radiometric results computed with this method compared to space-based sensor measurements viewing auroral scenes.
