Combined catalogue of sulfur dioxide emissions

Sulfur dioxide (SO2) measurements from three satellite instruments (OMI-OMPS-TROPOMI) were used to update and extend the previously developed global catalogue of large anthropogenic SO2 emission sources and degassing volcanoes (Fioletov et al., 2016).

This version 2 of the global catalogue, which is described in Fioletov et al. (2022), covers the period of 2005–2021 and includes a total of 759 continuously emitting point sources. The catalogue has been posted at the NASA Global SO2 Monitoring web site.

The catalogue data show an approximate 50 % decline in global SO2 emissions between 2005 and 2021, although emissions were relatively stable during the last 3 years.
