Polar Bear UV Imaging of Airglow and Aurora - Image Processing and Results

Abstract

In late 1986, AFGL launched the Polar BEAR satellite, which was designed for UV imagery of the northern pole region. The AIRS scanning ultraviolet photometer aboard the satellite provides images of day and night auroral structures of unprecedented spectral and spatial resolution at 2 working spectral windows simultaneously. It is necessary to apply geometric and photometric corrections to the image in order to enhance and map it onto the ionosphere. Furthermore, satellite attitude corrections are imperative to assure that image coordinates are properly rotated to the real-time body reference system. To the best knowledge of the authors, this project is the first one to fully include geometric and photometric corrections to VUV images of the ionosphere. (aw)
