Diurnal and seasonal variability of CO2 and CH4 concentration in a semi-urban environment of western India

Abstract Amongst all the anthropogenically produced greenhouse gases (GHGs), carbon dioxide (CO2) and methane (CH4) are the most important, owing to their maximum contribution to the net radiative forcing of the Earth. India is undergoing rapid economic development, where fossil fuel emissions have...
