TROPOMI Volcanic SO2 Image Archive


This archive is not an exhaustive list of all volcanic emissions detected by TROPOMI. Particularly large or otherwise interesting events will be posted here as time permits.

Images presented in the SO2 column will typically display retrievals from the current operational SO2 algorithm. In some cases, offline experimental algorithms may be implemented. Units are milli-atm-cm, also known as Dobson Units (DU), where 1 milli-atm-cm = 1 DU = 2.68x1016 molecules cm-2 at STP (0o degs C, 1013.25 hPa). Images in the Ash/Aerosols column show the TROPOMI Aerosol Index (AI), which is positive for UV-absorbing aerosols such as volcanic ash, and can be negative for non-UV absorbing aerosols such as sulfate. Note that the scale used varies between plots. For further information please contact us.
