Data source

The data for this month are from the TOMS instrument on the Soviet-built Meteor-3 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) assimilation, produced by the Goddard Earth Observing System Data Assimilation System (GEOS DAS). MERRA uses a version of the GEOS model with the Gridpoint Statistical Interpolation (GSI) atmospheric analysis developed jointly with NOAA/NCEP/EMC.
