Data source
The data for this month are from the OMI instrument (KNMI / NASA) onboard the Aura satellite. They are the OMTO3d that have beene processed in a manner similar to the TOMS data from earlier years.
Missing areas (bad orbits and polar night) are filled from an atmospheric model. The GEOS-5 FP data are produced by the Goddard Earth Observing System Model, Version 5. This is a system of models integrated using the Earth System Modeling Framework (ESMF). The GEOS-5 DAS integrates the GEOS-5 AGCM with the Gridpoint Statistical Interpolation (GSI) atmospheric analysis developed jointly with NOAA/NCEP/EMC.
