High resolution global maps of trace gases from S-5P/TROPOMI

Global map of total vertical NO2 columns, averaged over the period 2018-2020.

The Copernicus Sentinel-5 Precursor (S-5P) satellite was launched in October 2017 and its onboard instrument TROPOMI has delivered many impressive views of the distribution of atmospheric constituents that are relevant to air quality and climate. Based on the results, UV-VIS retrieval experts at BIRA-IASB have produced high resolution global maps for the molecules nitrogen dioxide (NO2), sulphur dioxide (SO2), formaldehyde (HCHO) and glyoxal (CHOCHO). The maps show a wide range of natural and anthropogenic sources, mapped with more detail than ever before, due to TROPOMI's enchanced sensitivity and spacial resolution.

The maps can be freely downloaded and used without any restriction for non-commercial applications, excluding scientific publications. In case of public presentation of any kind (e.g. poster or talk), adequate credit to the UV-VIS Remote Sensing group of the Royal Belgian Institute for Space Aeronomy (BIRA-IASB) must be given.
