Assimilation Ionosphere Model
Abstract
Our main long-term goal is to develop an Assimilation Ionosphere Model (AIM) that provides reliable ionospheric specifications and forecasts. A secondary goal is to use the model to elucidate the physics associated with the creation, transport and decay of plasma density structures and to determine their effects on naval systems. Our main objective is to construct a physics-based, global, ionospheric specification-forecast model that is capable of ingesting a diverse set of real-time (or near real-time) measurements. The data to be assimilated include slant path TEC's from several Global Positioning System (GPS) satellites, highquality TEC's from selected satellites with radio beacons, in situ plasma parameters from the SSIES instrument package on the DMSP satellites, digisonde data from selected ground-based stations, and both line-of-sight UV emissions and deduced plasma parameters from the Naval Research Laboratory's SSUSI and SSULI instruments. After AIM is constructed, a secondary objective is to use the model to study the sensitivity of the ionosphere to a wide range of external forcing functions. Of particular interest is the determination of the conditions leading to the creation of plasma density structures and irregularities.
