Mission Status

TROPOMI on board the Sentinel 5 Precursor (S5P) is in Operational Mode. 

The TROPOMI instrument was successfully launched on 13 October 2017 at 11:27 CEST/09:27 UTC and has successfully completed a series of important calibration and instrument tests during the six-month Commissioning Phase which concluded at the end of April 2018. The instrument is now in nominal, operational mode. Here below, one of the first RGB images produced from TROPOMI data for 13 November 2017 (Image credit: KNMI). The first set of data products was publically released in mid-July 2018. More data products by the end of 2018 and beginning of 2019.

Notification to all S5P/TROPOMI NO2 data users: 

An upgrade in the NO2 processing (version 01.04.00) with improved handling of cloud pressure has been implemented on 2 December 2020 starting with orbit 16259. As a result, we expect an offset to be introduced in the tropospheric NO2 column record starting from this day. In general, we expect to see larger values over polluted regions as compared to version 01.03.02. Any users analyzing trends in TROPOMI NO2 data should use caution when comparing data from periods before and after this switch. This data record offset will be rectified once the reprocessed data series is made available. For a more detailed description please refer to the NO2 Product Readme File (PRF) and check out this link for an overview and access to sample data.
