The GMPE is formed of daily NetCDF files containing various fields including the median of the ensemble, the anomaly of each ensemble member from that median and the SST gradients from each product. Where we do not have permission to redistribute data, the anomaly and gradient fields are filled with the missing data indicator (which is found in the _FillValue attribute to the variables and is set to -32768). The median_type variable, which reveals which analysis supplied the median at each location, has also been filled with the missing data value.
File names for the GMPE files are in the form 20101231120000-UKMO-L4_GHRSST-SST-GMPEREAN-GLOB-v02.0-fv02.0.nc.The first eight digits give the year (first four digits) followed by the month and the day (two digits each). For the period June to August 2007 there are GMPE files that contain the ESA SST CCI demonstration product 1 in addition to the analyses compared over the full period of the long term product. These have GLOB_DM in their file names in place of GLOB.
