Improvement of AMSR-E SST by deconvolution

The substantial overlapping of adjacent AMSR-E footprints and low resolution of AMSR-E sensors make it possible to improve AMSR-E SST accuracy by deconvolution. The Wiener filter is suggested to compensate the influence of AMSR-E point spread function. Kashevarov's bank has been used as a test region. The noise and blurring have been considered as main sources of errors. As a standard we use SST based on IR MODIS data. It was shown that near Kashevarov's bank AMSR-E SST is higher than MODIS SST up to 3°К. Deconvolution of AMSR-E data can significantly reduce this kind of errors.
Keywords: sea surface temperature, AMSR-E sensor, improvement of SST accuracy, restoration problem, Wiener filter
