The current state and prospects of satellite hyperspectral atmospheric sounding

The paper presents a brief description of hyperspectral IR sounders installed onboard the operational polar-orbiting meteorological satellites EPS/Metop, Suomi-NPP, and Meteor-M. The results of the data quality and validation of the IASI/Metop IR-sounder measurements are considered. An overview of the methods and processing technologies of the measurements performed by these sounders is presented. These allow us to obtain different information products on the parameters of the atmosphere and underlying surface. We present the results of the IASI data assimilation in models of numerical weather forecasting from the leading foreign prognostic centers. We discuss the applicability of these data and the results of remote sensing in climate studies. The formulation of problems is presented in relation to an increase in the efficiency of the applied satellite data, which requires additional research.
