Polar Ultraviolet Imager, Key Parameters
The Ultraviolet Imager (UVI) is a small camera that detected and produced images of the ultraviolet light of the aurora, day and night. Key Parameter (KP) images are calculated at nominal 5-10 minute intervals at spacecraft altitudes above 6 Re. The UVI KP image is background subtracted and calibrated to radiance values (photon cm^-2 cm^-1). The data is a rectangular two-dimensional array (228 rows x 200 columns). Only a circular region of the rectangular array contains valid image data. The UVI KP Image Archive (http://tideuvira.nsstc.nasa.gov/uvi/kpgs-Data.htm) allows the user to look at all the KP Mosaics for a selected month. The gif or png plot files contain the up to 35 KP images taken with the LBHL filter. Reference images are also provided showing the location of the UVI field of view relative to continental outlines.
