Atmospheric methane column-mean mole fractions measured with ground-based Fourier-transform spectroscopy near Saint-Petersburg, Russia (59.9° N, 29.8° E) are compared with similar data obtained with the Japanese GOSAT satellite in years 2009–2012. Average CH4 mole fractions for the GOSAT data version V01.xx are by −13 ppb less than the corresponding values obtained from ground-based measurements on the same date (with standard deviation ~ 26 ppb). For the GOSAT data version V02.xx the average difference is ~ 4 ppb and standard deviation ~ 15 ppb. This shows that FTIR spectroscopic observations near Saint-Petersburg could agree with GOSAT satellite data.
