information about the conversion of the data and the variables, scenarios and models
What we did to convert the data
We selected several longitude-latitude-boxes(one per continent) out from the original NetCDF-files and put them into the Grib-format to save memory by using PINGO and CDO (see tools). This was all done by using a self-written shell-script.
Unfortunately both programs are unable to produce the right grids and dates. Therefore the shell-script has rewritten the correct grid description files and fixed the date-problem: The shell-script took the original grid descriptions out of the NetCDF-files and put them into PINGO conforming grid description files which were used to set correct grids. Then the script set the right dates by moving the dates out of the original NetCDF-files into the correct date-format for PINGO. After that PINGO put the dates into the Grib-files.
At the end we sorted the data by continent, variables, scenarios and models.
