The first results of comparative measurements of altitude profiles of concentrations of carbon dioxide and methane from the aircraft laboratory YAK-42D "Roshydromet" are presented. The data were obtained both in real time using devices operating on the basis of diode laser spectroscopy and in laboratory conditions with the use of a Fourier spectrometer by processing air samples collected in special flasks during research flights.
