Abstract
We discuss the technology of data processing for the AIRS hyperspectral suite and AMSU-A microwave sounder installed on board the Aqua satellite. This technology makes it possible to retrieve geophysical parameters of the Earth’s atmosphere and surface even with 80 % coverage of an observation area by clouds. The failure of the AMSU-A sounder in 2016 led to exclusion of its readings from the AIRS data processing scheme and to implementation of the simplified AIRS Only algorithm used today by NASA. In this paper we propose an approach to repair the AIRS «all-weather mode» using data from the ATMS scanning microwave radiometer on board the Suomi-NPP and NOAA-20 satellites. It is shown that the inclusion of the ATMS readings in the data processing algorithm makes it possible to obtain geophysical results that practically coincide with the original AIRS/AMSU data.
