- Abstract
Carbon Dioxide (CO2) is one of the most important greenhouse gases after water vapor (H2O) which plays significant role in the climate process. Measurements of CO2 must meet the precision requirement 1\% in order to accurately infer the location of CO2 sources and sinks. GENSPECT, a line-by-line radiative transfer code, was used to investigate the top-of-atmosphere radiance change for 1\% CO2 variation in the atmospheric boundary layer (ABL) near the band 1580 nm. Findings suggest that the required signal-to-noise ratio (SNR) must be 2000:1 for Argus 1000 micro-spectrometer to detect 1\% CO2 change in the ABL. Laboratory experiments shows that Argus 1000, with SNR 1693:1, can detect 1.18\% CO2 change in the ABL.
