EUV online quality monitoring

The figure below shows the mean erythemal daily dose for the EUV/SEVIRI region (blue) together with the climatological mean and +- 1 std shading (gray) computed for each day of year from years 2004-2023. Deviation of current data from the climatological range suggests problems in the satellite measurement or data processing. Note that the region was changed on 26 Feb 2026 and SEVIRI calibration was changed on 16 Mar 2026.
