New 40-Year Global Ozone EDSR Released

MEaSUREs PI Dr Richard McPeters announces a new long term multi-sensor ozone ESDR (Earth Science Data Record), a unified ozone time series usable for trend analysis, is now available to users from the GSFC (Goddard Space Flight Center) GES DISC (Goddard Earth Science Data and Information Services Center).  The new ESDR includes reprocessed monthly zonal means of  atmospheric ozone vertical distribution and total column ozone data for the entire record from 8 SBUV (Solar Backscattered Ultra-Violet) instruments: Nimbus 4 BUV, Nimbus 7 SBUV, and SB

UV/2 on NOAA 9, 11, 14, 16, 17, and 18. The reprocessing employed a consistent radiance calibration, including correction for latitude/solar zenith angle dependence, for these 8 instruments spanning a 40-year period of operation (1970-2010). The consistent calibration is essential for analysis of trends in the Arctic and Antarctic. Data from NASA's NPP (NPOESS [National Polar-orbiting Operational Environmental Satellite System] Preparatory Project) OMPS (Ozone Mapping and Profiler Suite) instruments will be incorporated into the time series. This ESDR establishes a strong "truth" data set for model comparison, and are intended for use in the next WMO (World Meteorological Organization) report: Scientific Assessment of Ozone Depletion 2014.
