Abstract

This paper details recent advances in modeling and imaging capabilities since the work of Cox et. al. and Strickland et. al. The emphasis of current work is on simulating imaging data to be obtained by instruments such as SSUSI (spectral sensor ultraviolet spectrographic imager) on DMSP (Defense Meteorological Satellite Program), UVISI (ultraviolet and visible imaging and spectrographic imagers) on MSX (Midcourse Space Experiment) and GUVI (global ultraviolet imager), an instrument selected for NASA's TIMED mission. Some of the modeling capability to be discussed is presently being used to analyze dynamics explorer far ultraviolet images. Modeling improvements include the ability to efficiently calculate radiances as a function of solar azimuth in addition to zenith viewing angle, to calculate radiances for non-spherical density distributions of absorbing species, to input new model atmospheres, ionospheres, and auroral oval precipitation parameters, and finally, to access our radiance models through a much improved user-interface within a windows environment. Key improvements to our imaging software allow for limb and disk emission in global displays, easier mapping of information onto any one of several projections, and displaying simulated dayglow, nightglow, and aurora in full orbit `strip' images (distance along the orbit versus cross-track look angle or distance) as will be obtained by SSUSI. The above improvements are discussed with the aid of figures which show important solar azimuth effects, simulated global DE-1 130.4 nm data, geometrical projections that allow one to visualize the portion of the globe viewed by a low Earth polar orbiting sensor like SSUSI, and full orbit images of simulated SSUSI disk and limb data.
