UV-Visible DOAS Research

The UV-Vis DOAS group

The DOAS group concentrates on atmospheric chemistry related research, based on observations performed using the so-called Differential Optical Absorption Spectroscopy (DOAS) technique. Retrieval algorithms applied to ground-based and satellite instruments are developed and used to monitor the atmospheric concentration of a number of important trace gases like O₃, NO₂, BrO, OClO, HCHO, SO₂, CHOCHO, etc. These activities are performed in the context of the BIRA-IASB contribution to international ground-based networks (e.g. the NDACC) and to European atmospheric chemistry satellite missions like ERS-2/GOME, SCIAMACHY and GOME-2.

The group is lead by Dr. Michel Van Roozendael. See the members of our group here

 Sentinel-5p first light: first TROPOMI results.

Today, the first scientific results were presented from measurements of the TROPOMI satellite instrument, launched last October on-board the Sentinel-5P platform. During an ESA press event, organised at the German Aerospace Center DLR, a range of images and animations were shown, demonstrating the unprecedented spatial resolution delivered by the TROPOMI sensor.
