Abstract : This report describes the DMSP Sensor Fusion algorithm for remote sensing of the Auroral E-layer using the SSUSI and SSJ/5 sensors to be flown on Block SD DMSP satellites. It is a generalization of the SSUSI Single Sensor Auroral E-layer Algorithm described in an earlier report (PL-TR-94-2195) with many new capabilities. The algorithm analyzes SSJ/5 precipitating electron and ion data to characterize the precipitation parameters along the satellite track. It maps this information to the corresponding pixels of the SSUSI image and combines the SSJ/5 and SSUSI data to characterize the neutral composition along the satellite track. Using this information, the algorithm extrapolates the neutral composition information to off track pixels and uses this information as input to an improved single sensor algorithm. The data products provided by the algorithm include electron and ion precipitation characteristics (mean energy, energy flux), O to N2 and O2 to N2 ratios, and E-layer characteristics (peak density and height of the peak) for each pixel in the SSUSI image.
