N2 - The study of climate change based on spectral radiances of outgoing infrared radiation measured by different space-borne spectroradiometers, requires careful intercalibration of these instruments. The results of SI-1/Meteor-28(-29) (1977, 1979) and IKFS-2/Meteor-M N2 (in orbit operation since 2015) FTIR spectrometers intercalibration are presented in this paper to clarify the results of IR atmospheric spectra changes over the past 40 years, previously obtained by authors. The double-difference method is applied due to the impossibility of direct (synchronous) comparisons. Calculations of the infrared atmospheric spectra based on the radiosonde data and carbon dioxide data carried out using the LBLTRM radiation code are used as reference measurements. It was found that both the mean and standard deviation for double differences after selecting the most reliable measurements do not exceed 1–2 mW/(m2•sr•cm–1) in almost the entire spectral range under consideration 660–1350 cm–1, which indicates a good calibration agreement between two instruments.
