MEaSUREs GOZCARDS stratospheric data records update

Data products are now available of ozone, water vapour, nitric acid and nitrous oxide.

The Goddard Earth Sciences Data and Information Services Center (GES DISC), in collaboration with Principal Investigator Lucien Froidevaux, is pleased to announce the release of the ozone (O3), water vapor (H2O), nitric acid (HNO3) and nitrous oxide (N2O) zonal means data products from the "Global Ozone Chemistry and Related trace gas Data Records for the Stratosphere (GOZCARDS)" project, part of the NASA Making Earth Science Data Records for Use in Research Environments (MEaSUREs) Program. These products include monthly merged and source data for the above species (with start year being 1979 for O3, and later for other species).

Additionally, data for 2011 and 2012 from the previously released hydrogen chloride (HCl) and “MERRA-based” temperature (T) zonal mean data products are now available.

Other GOZCARDS products are planned for later in 2013. Users should review the README document for additional information. Information on these data, including the README document, and access to the data are available at
