Linear retrieval of SO2 column amount. Refer to: https://doi.org/10.5194/amt-4-1567-2011

* This webpage shows the output of the linear SO2 retrieval developed by the Earth Observation Data Group (EODG) at the University of Oxford. The retrieval methodology is described in Walker et al. (2011, 2012). This retrieval is able to flag pixels which contain elevated levels of SO2 by separating the SO2 signal from the spectral background. The method makes several assumptions and is only used for detection, rather than quantitative analysis. The output of the retrieval is gridded and saved as a .tif file which can be downloaded and plotted.
* The interactive map and the latest plots show the retrieval output for the last 24 hours. This is updated every five minutes.
* It is possible to search our historical record which currently covers 2007 to 2021 (see below the map).
