Variation characteristics of atmospheric greenhouse gases in Hefei region based on ground-based remote sensing and in-situ surface measurement
Based on ground-based Fourier transform infrared remote sensing and in-situ surface measurement, the variation of atmospheric CH4 and CO2 concentrations in Hefei City, China, from January 2016 to December 2017 were investigated. The observation results show that there were obvious seasonal variations in CO2 and CH4 over Hefei. CO2 showed a minimum value in August 2016, and then gradually increased over time, reaching the maximum in April 2017. After that, it declined gradually, reaching another minimum value in early September 2017. In contrast, CH4 showed high level in summer and early autumn, and low concentrations in winter and early spring. In 2016, the seasonal amplitudes of the monthly mean concentrations of XCO2 and XCH4 measured by ground-based remote sensing were 5.96
