Water vapour columns are retrieved from GOME data using the Air Mass Corrected Differential Optical Absorption Spectroscopy (AMC-DOAS) method. This is a variant of the standard DOAS method used for the retrieval of strong absorbers which accounts for nonlinearity and airmass factor in the fit.
For more information and data please visit the AMC-DOAS home page.
Data files are available via the AMC-DOAS data page.
