AB: Because of long nitric oxide lifetimes and the importance of transport in understanding local observations, production (and thus particle precipitation) must be known on a global scale. Observations of particle precipitation are being or have been collected from space-based imagers and in-situ particle detectors (i.e., on IMAGE, TIMED, DMSP, NOAA POES, FAST) and by recently expanded and enhanced ground-based sensor networks in celebration of the International Polar Year (i.e., AARDDVARK, GLORIA, etc.). These resources and upcoming new missions allow a robust, and flexible assessment of global precipitation from auroral to radiation belt energies, from the polar to the equatorial regions by developing assimilation techniques, which do not depend on any one data source. To explore the requirements and the potential of this type of assimilative effort in advancing our understanding of system behavior and coupling between the upper and middle atmospheric regions, this presentation draws together observations of precipitating populations from a variety of data sources during the 15-30 Jan 2005 long duration flare events and magnetic activity including several solar particle events, auroral, radiation belt, ring current and mid-low latitude ion-atom precipitation as well as high energy intense polar rain. A preliminary evaluation of the relative potential of each population for disrupting stratospheric ozone will be undertaken.
