OMPS processing use the new OMTO3 v2.1 and SO2 PCA v1.1 algorithms (since 21th Aug 2018). Because of this, OMPS HDF5 data structures are different from the earlier versions.

!!! The new SW has instabilities and thus, some of the overpasses are not processed. We try to solve this as soon as possible.

These pages provide direct readout satellite data of the Northern Hemisphere atmosphere. The measurements are from the OMI and OMPS instruments, published about 15 min after overpasses of the EOS-Aura and Suomi-NPP satellites. The OMI data are received at Sodankylä, Finland, and the OMPS data at Sodankylä and Fairbanks, Alaska.

The products include: O3, SO2, clouds, UV index, UV daily dose and aerosols.
