(3) Large-scale and convective precipitation are not required if total precipitation is provided (and viceversa)
(4) Runoff is not required if both surface and sub-surface runoff are provided (and viceversa)
(!) Those names are not included within the list of CF standard_names, but they have been derived from existing standard names (toa_incoming_shortwave_flux, toa_net_downward_longwave_flux) following the Guidelines for Construction of CF Standard Names
NOTES:
- Accumulations in GRIB are made from the beginning of the forecast, while in netCDF they are made accordingly to the description contained in the cell bounds/methods
- In netCDF, cell bounds and methods are also used to appropriately define maximum/minimum, etc.
