Global Monitoring for Environment and Security (GMES) is a joint initiative of the European Community and of the European Space Agency. The Declaration on the GMES Space Component Programme provides that the Sentinel-5 Precursor mission is planned to be implemented in co-operation with the Kingdom of the Netherlands, which in the frame of the development of the TROPOMI Instrument, will provide the Ultraviolet-Visible-Near-Infrared instrument as a national contribution. The Sentinel-5 Precursor is a UV-VIS-NIR-SWIR spectrometer atmospheric chemistry mission derived through tailoring of Sentinel-5 specifications with priority on spectral resolution, coverage, spatial sampling distance, signal-to-noise ratio and only high priority bands. The paper provides a description of the Spacecraft and an outline of the Ground Segment concept.
