Parameters forming part of the Climate Change Adaptation Digital Twin (DT) are investigated here. See the encodings below, which are current for ecCodes 2.32.8/2.34.3.
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)
