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 TROPOMI air quality measurements

On 19 June 2018, a press conference was held at BIRA-IASB to present the first results from the TROPOMI instrument on-board the Sentinel-5 Precursor satellite. TROPOMI, (the TROPOspheric Monitoring Instrument has been monitoring the whole of Earth's atmosphere on a daily basis ever since its launch in October last year. Belgian scientists are strongly involved in the analysis of the data and can now present the first formidable results of the instrument's air quality measurements.
