Abstract
The Tropospheric Monitoring Instrument (TROPOMI) is being developed for launch in 2014 on GMES Sentinel 5 Precursor satellite. Global Monitoring for Environment and Security (GMES) is a joint initiative of the European Community (EC) and of the European Space Agency (ESA). TROPOMI is a passive sun backscatter spectrograph using the ultraviolet-to-SWIR wavelengths to have good sensitivity down to the surface. Together with its spatial resolution of 7 x 7 km2 it allows good observations of sources and sinks of air quality and climate related gases and aerosols. This spatial resolution results in a high fraction of cloud-free observations and is combined with a wide cross-flight swath to allow daily coverage of the complete Earth. The instrument has as predecessors the OMI instrument (Ozone Monitoring Instrument) on NASAs AURA satellite and the SCIAMACHY instrument on ESAs ENVISAT, where the push broom concept is derived from OMI and the SWIR observations from SCIAMACHY. The wavelength bands of TROPOMI are a UV band (270 - 320 nm) for the ozone profile and SO2 products, a UVIS band (320 - 500 nm) for O3, NO2, BrO, HCHO and OClO total columns, a NIR band (675 - 775 nm) for clouds and H2O columns and a SWIR band (2305 - 2385 nm) for CH 4 and CO columns and the HDO/H2O ratio. The paper will give an overview of the challenges and current performances. The TROPOMI UVN module is funded by the Netherlands and the SWIR module and platform is provided via ESA. The instrument development is now a truly European programme with contributions from several countries. © 2011 SPIE.
