| 摘 要： | Infrared solar spectra on clear days were measured automatically by an infrared solarspectrometer(ISS)with 0.4 cm~(-1) resolution developed by us.A line-by line(LBL)computationmethod was used to calculate theoretical atmospheric absorption.In the wavelength range of 3.410—3.438 μm.the absorption is mainly due to atmospheric methane and water vapor.Columnatmospheric methane was retrieved from the recorded infrared solar spectra.The seasonal variationof column atmospheric methane in Hefei has been obtained from the measuremental data of nearly18 months since the April of 1997.and found that it is similar to that of background data.Theinstruments.principles of measurement and some of results were introduced,and the results arealso discussed briefly in the paper.
