Characterization of Tropospheric Emission Spectrometer (TES) CO2 for carbon cycle science
Atmospheric Chemistry and Physics
We present carbon dioxide (CO 2 ) estimates from the Tropospheric Emission Spectrometer (TES) on the EOS-Aura satellite launched in 2004. For observations between 40 • S and 45 • N, we find about 1 degree of freedom with peak sensitivity at 511 hPa. The estimated error is ∼10 ppm for a single target and 1.3-2.3 ppm for monthly averages on spatial scales of 20 • ×30 • . Monthly spatially-averaged TES data from 2005-2008 processed with a uniform initial guess and prior are compared to CONTRAILdoi:10.5194/acp-10-5601-2010 fatcat:7nnp75ov25drrow3wdz4xyrvta
