Total sulfur dioxide emissions, monthly
What it measures. Monthly estimates of total sulfur dioxide emissions from all sources combined, mapped at roughly 1-degree resolution, for 2005 to 2021.
How it's made. Produced by a chemical reanalysis (TCR-2) that blends multiple satellite sensors with models to simultaneously estimate both pollution amounts and their emissions.
How & where you'd use it. Useful for tracking sources of air pollution over time, studying air quality, and informing emissions and climate research.

Official description
The TROPESS Chemical Reanalysis Surface Total SO2 emissions Monthly 2-dimensional Product contains sulfur dioxide emissions from the total of all sources. The data are part of the Tropospheric Chemical Reanalysis v2 (TCR-2) for the period 2005-2021. TCR-2 uses JPL's Multi-mOdel Multi-cOnstituent Chemical (MOMO-Chem) data assimilation framework that simultaneously optimizes both concentrations and emissions of multiple species from multiple satellite sensors. The data files are written in the netCDF version 4 file format, and each file contains a year of data at monthly resolution, and a spatial resolution of 1.125 x 1.125 degrees. The principal investigator for the TCR-2 data is Miyazaki, Kazuyuki.
