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

 FRM4DOAS: A centralized MAX-DOAS processing system in support of satellite validation

To harmonise the MAXDOAS data sets measured all over the world, the Fiducial Reference Measurements for ground-based DOAS Air-Quality Observations (FRM4DOAS) project was set up as a demonstration project providing a centralized rapid-delivery (24 hour latency) processing service for a selection of MAX-DOAS instruments.
