Abstract
The sensitivity of satellite thermal infrared hyperspectrometer readings to variations of the atmospheric gas constituent amounts is considered. It is shown that the differential sensitivity coefficients of the instrument channels to variations in the density of the gas of interest is expressed through the mass absorption coefficient of this gas and an universal function which is determined by the intensities of the outgoing radiation for the unperturbed atmosphere. The numerical values of the universal function, as well as the methane and ozone differential sensitivity coefficients for the AIRS/Aqua channels, obtained with the use of Line-By-Line Radiative Transfer Model, are presented.
