TROPOMI - the Instrument
Long-term monitoring is essential for climat research and for monitoring the effect of the measures of the Montreal Protocol. In order to prepare for the period after 2010, when OMI on Aura and SCIAMACHY on ENVISAT have reached their end-of-life, the OMI and SCIAMACHY participating parties in the Netherlands are designing an innovative UV-VIS-NIR-SWIR imaging spectrometer. The instrument concept has been proposed for two missions:
- TROPOMI on TRAQ, a mission proposed in response to ESA’s 2005 EOEP call.
- TROPI on CAMEO, as specified in a proposal for the U.S. NRC Decadal Study on Earth Science and Applications from Space.
Apart from these proposals, the instrument concept fits closely to the formulation of ESA’s CAPACITY study to realize a LEO mission with a UV-VIS-SWIR nadir viewing spectrometer (Sentinel 5).
TROPOMI: the best of two worlds
TROPOMI is a Dutch national inititive that builds on the successes of SCIAMACHY, GOME and OMI. TROPOMI combines the large viewing angle of OMI with the large wavelength range of SCIAMACHY. TROPOMI will play a key role for future climat research and air quality measurements.
