Offline Validation of Total Ozone Column

Validation Information

Offline GOME2/MetopA, GOME2/MetopB and GOME2/MetopC Total Ozone Columns are routinely downloaded from the DLR Earth Observation Center whereas the IASI/MetopA and IASI/MetopB Total Ozone Columns are periodically provided by the Laboratoire Atmosphères, Milieux, Observations Spatiales, LATMOS, and the Université Libre de Bruxelles, ULB, and are analysed using the FORLI-v2015 algorithm.  Both are validated against quality-assured ground-based Brewer, Dobson and M-124- Total Ozone Columns routinely deposited in the World Ozone and Ultraviolet Data Centre. 

Furthermore, official NASA OMI/Aura [OMDOAO3 & OMTO3] Total Ozone Columns are downloaded from the Aura Data Validation Center and are similary analysed. 

For historical and comparative purposes, official ESA SCIAMACHY/Envisat SGP5.02 Total Ozone Columns are also shown, as well as NASA TOMS/EP v8.5, downloaded from ESA Earth OnLine and NASA Ozone and Air Quality respectively. 

The comparative datasets are updated monthly.
