UV-Visible DOAS Research

The UV-Vis DOAS group

The DOAS group concentrates on atmospheric chemistry related research, based on remote-sensing observations performed using the Differential Optical Absorption Spectroscopy (DOAS) technique. Retrieval algorithms applied to ground-based, airborne and satellite instruments are developed and used to quantify the abundance of atmospheric trace gases such as O3, NO2, SO2, HCHO, CHOCHO or HONO, which all play an important role for air quality and climate change related studies. These activities are performed in the context of international ground-based networks (e.g. NDACC and ACTRIS) and in support of various environmental research programmes such as the ESA Climate Change Initiative and the Copernicus programme of the European Union.

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


Recent highlight  (previous)

 The SIJAQ campaign in South Korea.

The Geostationary Environmental Monitoring Spectrometer (GEMS) was launched into space by the National Institute of Environmental Research (NIER) and the Ministry of Environment of Korea, on board the GEO-KOMPSAT 2B satellite in 2019. GEMS is one of three air quality monitoring missions over the Asian continent. To validate the measurements from this instrument, two ground based campaigns have been organized so far: SIJAQ/GMAP in 2021 and SIJAQ 2022 this year.
