Welcome to the EOC Geoservice


The EOC Geoservice of the Earth Observation Center (EOC) of the German Aerospace Center (DLR) provides discovery, visualization, and direct download services for a selection of the geospatial data hosted by the German Satellite Data Archive (D-SDA). Based on web technologies and running on high-performance hardware large geospatial datasets can be accessed through the EOC Geoservice. To find out more, see the About page or take a look at the Geoservice Flyer.

Sentinel-5P TROPOMI L3 Composites released

Posted on Jul 6, 2018 by Administrator

The TROPOMI instrument is a space-borne, nadir-viewing, imaging spectrometer covering wavelength bands between the ultraviolet and the shortwave infra-red. TROPOMI is the single payload of the SENTINEL-5P spacecraft, the purpose of which is to measure atmospheric properties and constituents. The instrument uses passive remote sensing techniques to attain its objective by measuring at the Top Of Atmosphere (TOA) the solar radiation reflected by and radiated from the earth. TROPOMI can measure a range of atmospheric trace constituents, as well as cloud properties. These data are crucial for monitoring the atmospheric composition and the detection of pollutants. The German Aerospace Center (DLR) is responsible for the payload ground segment of the Sentinel-5P mission and together with the Royal Netherlands Meteorological Institute (KNMI) also engaged in the processing and analysis of the satellite data. The TROPOMI measurement data go through a highly complex processing chain: The raw measurements are received by the ground stations and transmitted to DLR. There they are analyzed, filtered, processed into individual data products and automatically made available on a web server. The processing system was developed by the Remote Sensing Technology Institute (IMF) of DLR and KNMI. DLR operates the processors and ensures that the partly interlinked work steps are running smoothly.
