Welcome to the XML aggregator wiki!

The output of this package is a tree of XML files that point to locally-indexed CMIP6 netcdf data. An example filename is:

CMIP6.CMIP.historical.NOAA-GFDL.GFDL-CM4.r1i1p1f1.mon.zg.atmos.glb-p19-gr1.v20180701.0000000.0.xml

The components (separated by . delimiters) of this filename identify:

CMIP6 – mip era
CMIP – activity (umbrella for different experiments)
Historical - experiment
NOAA-GFDL - institution
GFDL-CM4 - model
r1i1p1f1 – realization
mon - frequency
zg - variable
atmos – realm
glb-p19-gr1 – grid label
v20180701 – version
0000000 – warning flags (could be used for diagnosing issues with cdscan)
0 – latest flag (not used)

This then indexes data that is located in the LLNL-ESGF CMIP6 project space, following the CMIP6 Data Reference Syntax (DRS, described here) and following the directory path:

../CMIP6/CMIP/NOAA-GFDL/GFDL-CM4/historical/r1i1p1f1/Amon/zg/gr1/v20180701

The netcdf files that the XML spans are named:

zg_Amon_GFDL-CM4_historical_r1i1p1f1_gr1_185001-194912.nc
zg_Amon_GFDL-CM4_historical_r1i1p1f1_gr1_195001-201412.nc
