The Sentinel-5 Precursor mission is intended to provide data continuity for the SCIAMACHY instrument aboard the Envisat satellite and NASA's OMI instrument aboard the Aura satellite in the interim between the end of the Envisat and Aura missions and the launch of Sentinel-5. With no other missions capable of obtaining the data acquired by SCIAMACHY and OMI, Sentinel-5P fills what would be a five-year gap until the launch of Sentinel-5.

The mission will perform atmospheric monitoring at high temporal and spectral resolution, and increased cloud-free observation.

It is a joint initiative between ESA and the Kingdom of the Netherlands providing the TROPOMI UV-VIS-NIR-SWIR instrument.

TROPOMI is an advanced spectrometer that will be provided in a co-operative effort funded by the Dutch Ministry of Economic Affairs and with instrument development lead by Dutch Space.
