Description

https://github.com/NCAR/WrfHydroForcing/blob/b67cbe88b4ae8daf5e82a5afe7d21fddfe2410ee/core/config.py#L403

I found out that the forecastMod.process_forecasts won't run if my configure doesn't have forecast flag on. But I'm not running for a real time instance; instead, I want to regrid and downscale the metrological forcing (except for the rainfall) for the past event (eg., 2016-2020) from NARR.

Research direction

Start with core/config.py around line 403 and trace the forecast flag into forecastMod.process_forecasts. Determine how retrospective and reforecast runs are expected to differ for historical NARR forcing, especially when rainfall is excluded. Done should clearly define the supported behavior for the 2016–2020 use case and verify it against the relevant processing path.
