Near real time data

Data from the Infrared Atmospheric Sounding Instruments (IASI) on board ESA's MetOp-A and MetOp-B satellite platforms are displayed as analysed for the presence of volcanic SO2 in the atmosphere, using methods developed by the Earth Observation Data Group at the University of Oxford.
The data are available in near real time, within ~ 3 hours of the measurement being made by the instrument. The previous 48 hours of data are avialable below. We also have an archive of all the data from IASI.
