Data source

The data for this month are from the OMI instrument (KNMI / NASA) onboard the Aura satellite. They are the OMTO3d that have been 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.

Palette relating map colors to ozone values

The false-color view of the monthly-averaged total ozone over the Antarctic pole. The blue and purple colors are where there is the least ozone, and the yellows and reds are where there is more ozone.


A week begins with Sunday. Fainter images are shown in the previous and following months. Missing days are indicated with a plain gray globe.
