Data source

The data for this month are from the TOMS instrument on the NASA/NOAA Nimbus-7 satellite.

Missing areas (bad orbits and polar night) are filled from an atmospheric model. MERRA is a NASA reanalysis for the satellite era using a major new version of the Goddard Earth Observing System Data Assimilation System Version 5 (GEOS-5). The Project focuses on historical analyses of the hydrological cycle on a broad range of weather and climate time scales and places the NASA EOSsuite of observations in a climate context.
