On 13 October 2017, the European satellite Sentinel 5 Precursor was launched, with on board the TROPOspheric Monitoring Instrument TROPOMI. The mission targets societal challenges on air quality, climate and the ozone layer.

TROPOMI is an imaging spectrometer measuring in the ultraviolet, the visible, the near infrared and the shortwave infrared, and was developed by The Netherlands and the European Space Agency (ESA). TROPOMI measures a range of atmospheric  gases, including ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide and methane. In addition, TROPOMI also provides information about particulate matter, clouds and surface properties. New aspects of TROPOMI include the high spatial resolution (3.5 km x 7 km for most bands), in combination with a high signal-to-noise ratio. The instrument inherits the measurements principles that provides daily global coverage, from its successful predecessor OMI.

In this presentation, the TROPOMI instrument will be discussed, as well as the principles of the data processing algorithms. Results of the first year in orbit will be presented.
