In the framework of different atmospheric missions (cf. GOME-2, and the EU Copernicus Missions Sentinel-5 Precursor (S5P), Sentinel-4, Sentinel-5) DLR’s Remote Sensing Technology Institute develops algorithms for the accurate derivation of ozone and other trace gases (e.g. NO2, SO2, HCHO, CHOCHO) as well as aerosol and cloud properties from satellite data obtained with GOME- and OMI-type atmospheric spectrometers. These algorithms are used operationally in near-real-time processing systems of ESA, EUMETSAT and the DLR AC-SAF. At the end of 2017, the TROPOMI instrument was launched on board the EU/ESA Copernicus satellite S5P, followed in 2018 by the third GOME-2 sensor on EUMETSAT's MetOp-C platform.
The Remote Sensing Technology Institute has many years of experience in deriving atmospheric products from satellite measurements ranging from GOME/ERS-2, SCIAMACHY/ENVISAT, GOME-2/METOP to TROPOMI/S5P and continuing in the future with the Copernicus Sentinel missions Sentinel-4 and Sentinel-5.
