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/TROPOMI: Mapping air quality in unprecedented detail

Last week, on October 13, 2017, the European satellite Sentinel-5 Precursor (Sentinel-5p) was launched from the Russian Cosmodrome of Plesetsk on behalf of the European Space Agency (ESA). Its payload contains a single instrument, the TROPOspheric Monitoring Instrument (TROPOMI), that is designed to analyse the chemical composition of the Earth's atmosphere in unprecedented detail. The UV-VIS/DOAS group and other scientists from the Royal Belgian Institute for Space Aeronomy (BIRA-IASB) are strongly involved in the analysis of TROPOMI's data.
