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 a series of important calibration and instrument tests were successfully completed 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 with more data products released at the end of 2018 and in early 2019. Detailed reports about mission status and an overview of data gaps is available here. An RSS Feed is available here for announcements of important mission and processing changes.
Notification to all S5P/TROPOMI NO2 data users:
The upgrade to version 2.2.0 (5 July 2021) leads to an increase of the tropospheric NO2 columns for cloud-free pixels. The previous upgrade to version 1.4.0 (2 December 2020) led to a substantial increase in the observed tropospheric NO2 column amounts over polluted areas for scenes with small cloud fractions. Studies including both data before and after the activation of these versions will therefore show artificial (positive) jumps. For time series, trend studies or comparisons between years the results from the latest versions 2.2.0 and 1.4.0 should not be mixed with results from the older versions without accounting for these changes. 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.
Instrument and Data Status
A calendar summarizing important mission events and instrument-wide anomalies can be found here. All aspects of S5P mission requirements for quality control, calibration, validation, and end-to-end system performance monitoring are addressed by the so-called S5P Mission Performance Centre (MPC), further described here.
