Parameters forming part of the Weather and Geophysical Extremes Digital Twin (DT) are investigated here. See the encodings below, which are current for ecCodes 2.3335.0.

Warning

title	Data availability

Currently only the fields in Secn 1.1.1 and 1.1.2 are available on the LUMI databridge as part of the first production-like ExtremesDT runs.

This is currently in class=rd,expver=i7yv,stream=oper,type=fc

See the Extremes DT overview page for more details on data availability and accessing the data.

title	Additional keys

Please note that additional keys are often necessary in addition to the base parameter definition below. For example for:

statistical processing (e.g. time interval of processing)
level information (e.g. a given pressure level, say 300 hPa)

Any entry with localTablesVersion=1 should not be used in production outside ECMWF.
