Welcome to the ASDI-CMIP6-DCPP-hindcast wiki!

met-office-cmip6 data on ASDI:

This data is a replica of hindcast data published for the Decadal Climate Prediction Project by the Met Office data to CMIP6 via ESGF. Data is stored in collections of netCDF4 files structured and organised according to the Directory Reference Syntax recorded in the Global Attributes documentation for CMIP6.

The directory structure is illustrated below

CMIP6/
    CMIP/MOHC/HadGEM3-GC31-MM/piControl/
        r1i1p1f1/
            fx/
                [variable name]/
                    gn/vYYYYMMDD/
                        [files]
            Ofx/
                [variable name]/
                    gn/vYYYYMMDD/
                        [files]
    DCPP/MOHC/HadGEM3-GC31-MM/dcppA-hindcast/
        s<start year>-r<ensemble index>i1p1f2/
            [table id]/
                [variable name]/
                    gn/vYYYYMMDD/
                        [files]

The "fixed" variables, i.e. those that do not vary in time, included from the HadGEM3-GC31-MM piControl (pre-industrial control) simulation include orography (fx/orog) and land-sea mask.

The hindcast data includes simulations starting each year between 1960 and 2018, with 10 ensemble members for each year. For example to obtain the monthly mean surface temperature for the seventh simulation starting in 1998 look here.

Files are named using the following naming convention (see link to Global Attributes document above for full details);

<variable name>_<table id>_HadGEM3-GC31-MM_dcppA-hindcast_s<start-year>-r<ensemble index>i1p1f2_gn_<start date>-<end date>.nc

Data for each year is stored separately and the start and end date format is YYYYMM for most files with the exception of those in the day table (daily frequency) for which the format is YYYYMMDD.
