Gridded Global Surface Ozone Metrics data (1971-2015) for Atmospheric Chemistry Model Evaluation - version 2.7

This dataset consists of version 2.7 gridded surface ozone metrics for atmospheric chemistry model evaluation. These data have global coverage on both monthly and annual timescales from 1971-2015. Multiple model resolutions were used and can be easily identified within the filename.

Data are stored as NetCDF-4 files, with one file per model resolution at each time resolution. The files hold gridded surface ozone data from multiple databases (WMO GAW, EPA CASTNET, EPA AQS, Canadian CAPMON, Canadian NAPS, European EMEP, European AirBase, East Asian Acid Deposition Monitoring Network EANET), plus metadata. Metrics include the moments of the distribution, percentiles, maximum daily eight-hour average (MDA8), SOMO35, AOT40, and metrics related to air quality regulatory thresholds. In addition, metadata for all contributing sites (e.g. Site name, latitude, longitude) are included in each file.

Statement
Data were processed by the authors and delivered to CEDA for archiving. It appears that the file CCMI_SurfaceOzoneObs_1x1a_Annual_v2.7.nc is a compressed tar archive (usually filename extension given as a .tar.gz), but in this instant it has been incorrectly given the filename extension .nc. Even though the file is only 128MB when compressed, it expands to 21GB of uncompressed data, consisting of all the other netCDF files that are present in the same directory, /badc/proc-earth-model/data/ozone-metrics/v2.7. However, it does not contain a netCDF file called CCMI_SurfaceOzoneObs_1x1a_Annual_v2.7.nc and unfortunately not available for archiving.
