The paper presents the result of a retrieval of tropospheric carbon monoxide (CO) from infrared hyperspectral observations of AIRS/AMSU on board AQUA. The retrieval method is based on a modified double differential approach derived from AIRS/AMSU observations of the Far Easten territory of Russia in the fire-dangerous period. The main advantages and practical suitability of the modified double differential approach are discussed. Comparisons with NASA carbon monoxide data and ground-based measurements are well correlated. Mathematical expectation of deviation is 7.8% and standard deviation is 10% for NASA carbon monoxide data. Mathematical expectation of deviation is 8.9% and standard deviation is 4.7% for ground-based measurements. The ground-based measurements were made in Central Siberia by Forest Institute of the Siberian Branch of the Russian Academy of Sciences. The modified double differential approach opens the way for new theoretical research using national satellite instruments of infrared spectroscopy. In future, we plan to use this retrieval method for other atmospheric gases observed by infrared Fourier spectrometers on Meteor-M satellites board.
