Note: The "step" key (as well as startStep, endStep and stepRange) were added purely for the MARS system here at ECMWF and MARS only deals with steps in units of hours. |
The stepUnits key can only be set in the following situations:
- before encoding, in order to tell ecCodes what units are we dealing with
- when decoding, in order to tell ecCodes what units to get the step in
Examples:
