Abstract

Following successful launch of NPP satellite in October 2011, the VIIRS instrument started delivering high quality radiances from which improved Sea Surface Temperature (SST) products are generated. The design of VIIRS instrument is similar to the MODIS sensor, which includes a double sided mirror re ecting the Earth's radiance to 10 individual detectors. Despite pre-launch characterization and the use of on-board calibration systems, persistent discrepancies between detectors radiometric responses often lead to striping in the level 1 imagery, which is then propagated into level 2 derived geophysical products. The determination of calibration- based uncertainties in level 1 radiances is necessary to further improve the quality of ocean products. This paper characterizes radiometric errors between the multiple detectors and mirror-sides in MODIS and VIIRS thermal emissive bands. A unidirectional variational model is applied on several scenes corresponding to clear-sky top-of- atmosphere ocean radiances to extract the scan line noise due to potential detector-to-detector, mirror-side and random stripes. Data from Terra and Aqua MODIS and NPP VIIRS sensors is used to evaluate and compare the degree of stripe noise in emissive bands used to generate SST products.
