The efficiency of the use of a passive method for correlation of gas light filters for measuring the content of methane in the atmosphere in different spectral intervals is analyzed. The effect of atmospheric gases (Н2О, N2O) and air temperature on the measuring error is considered. The optimal concentration of methane in a correlation chamber of a space radiometer for measuring the total content of methane in the atmosphere is determined.
