Tropospheric ozone based on satellite measurements of sciamachy and gome

www.doas-bremen.de The SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric CHartographY) project is a German, Dutch and Belgian contribution to the ESA ENVISAT, which was launched on the 28th of February 2003. The instrument is a spectrometer designed to measure simultaneously sunlight, transmitted, reflected and scattered by the earth, atmosphere or surface in the ultraviolet, visible and near infrared spectral regions (e.g. 240 nm 2380 nm) at moderate spectral resolution (0,2 nm 1,5 nm dependent on channel). Mathematical inversion of the measurements yields the amounts and distributions of the following trace constituents and parameters: O , BrO, OClO, ClO, SO , 3 2
