Data source
The data for 1979–1993 are from the TOMS instrument on the NASA/NOAA Nimbus-7 satellite.
The data for 1994 are from the TOMS instrument on the Soviet-built Meteor-3 satellite.
The data for 1997–2004 are from the NASA Earth Probe TOMS satellite.
The data for 2005–2016 are from the OMI instrument (KNMI / NASA) onboard the Aura satellite. They are the OMTO3d (Global Ozone Data) data.
The data for 2017–2018 are from the OMPS instrument onboard the Suomi NPP satellite.
Missing areas (bad orbits and polar night) are filled using assimilated ozone data from the Modern-Era Retrospective analysis for Research and Applications (MERRA and Version 2 (MERRA-2) assimilations, produced by the Goddard Earth Observing System Data Assimilation System (GEOS DAS). MERRA and MERRA-2 use a version of the GEOS model with the Gridpoint Statistical Interpolation (GSI) atmospheric analysis developed jointly with NOAA/NCEP/EMC. Data are also filled using the GEOS FP data are produced by the Goddard Earth Observing System data assimilation system (DAS). The GEOS FP system integrates forefront versions of the GEOS atmospheric general circulation model with advanced data assimilation techniques, using a broad range of satellite observations.
