On 2 July an agreement between ESA and the Dutch Ministry of Economic Affairs was signed in The Hague on the Tropospheric Monitoring Instrument (Tropomi), confirming the latter as a national contribution for the GMES Sentinel-5 Precursor mission. Tropomi is an advanced imaging absorption spectrometer which will provide data on atmospheric trace gases and aerosols impacting air quality and climate.

The aim of the Sentinel-5 Precursor mission, planned for launch in 2014, is to fill the gap between the current atmospheric monitoring instruments – Sciamachy on ESA’s Envisat satellite and the Ozone Monitoring Instrument (OMI) carried on NASA’s Aura mission – as they are approaching the end of their missions and the launch of Sentinel-5 around 2020. Like Sentinel-4 and Sentinel-5, Sentinel-5 Precursor will be dedicated to atmospheric monitoring in the framework of the GMES Atmosphere Service.

Moreover, the agreement will launch the process of construction of the Tropomi, which will be carried out jointly by the Netherlands Space Office NSO, the Dutch Royal Meteorological Institute KNMI, the Dutch Institute for Space Research SRON, TNO and Dutch Space.
