CO columns from SCIAMACHY

CO columns from SCIAMACHY

The SCIAMACHY/ENVISAT near-infrared / short wave infrared (NIR/SWIR) nadir spectra of reflected and backscattered solar radiation contain information on the total vertical column of carbon monoxide (CO). At the University of Bremen we retrieve this information using a modified DOAS algorithm called WFM-DOAS. The latest version of our CO retrieval algorithm is WFM-DOAS version 0.6. So far we have processed three years of data (2003-2005).
