Carbon monoxide columns from SCIAMACHY

Carbon monoxide columns from SCIAMACHY

At the University of Bremen the dry air column averaged mixing ratio of carbon monoxide (CO) is retrieved from SCIAMACHY near-infrared nadir spectra using a DOAS algorithm called WFM-DOAS. The processing system is still under development and not yet fully operational and the data products have not yet been fully validated. Here some example results obtained from the WFM-DOAS algorithm version 0.6 are shown.
