The structure and main characteristics of the IR Fourier spectrometer IKFS-2 intended for measuring
of leaving radiation in the system atmosphere - surface on board of the satellite METEOR-M-2. Spectral
range is 5-15 μm, spectral resolution is 0.5 cm-1. Data obtained provide temperature profile in
troposphere and lower stratosphere with error of 1-1.5 K and vertical resolution up to 1 km in lower
troposphere, humidity profile in troposphere with error of 10% and vertical resolution 1-2 km in lower
stratosphere, total ozone concentration with relative error less than 5%, vertical profile of ozone
concentration in ozone layer with relative error of 10%, surface temperature with error of 0.5 K for water
surface and 1 K for land. In addition it is possible to obtain data for detection of total concentration of
small gaseous components in atmosphere: СН4, N2O etc.
Keywords: IR Fourier spectrometer, temperature and humidity profiles, troposphere, ozone layer, small gaseous components in atmosphere
