Data source
The data for this month are from the OMPS instrument onboard the Suomi NPP satellite.
Missing areas (bad orbits and polar night) are filled using assimilated ozone data. 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.
