Hello, I would like to conduct sensitivity test about terrain height on an em_real case. The number of domain are one.
The simulations preiod is from July 27, 1800UTC to July 29, 0600UTC. I want to evaluate the effact terrain height in the period just after July 28 0900UTC (Restart Time Point), which I was concerned.
I would like to restart using the wrfrst file and wrfbdy file at the Restart Time Point.
Because the conditions could change after modifying the terrain, I do not want to conduct a cold run from the earliest point, July 27, 1800 UTC.
And I don't want to start the run just several hours before the Restart Time Point using IC/LBC from the reanalysis dataset.
Since modifying the terrain height (HGT) would also influence the geopotential height and pressure in the model vertical coordinates, I think I should reconstruct the atmospheric state in the wrfbdy and wrfrst files so that they match the new vertical coordinates.
My question is: is there any solution to reconstruct the wrfrst file on a grid with changed terrain?
I want to use the state from the generated wrfrst and apply some interpolation solution (like real.exe).
As far as I'm concerned, real.exe interpolates the reanalysis fields into user-defined model levels.
I want to make an interpolation from the user-predefined fields into a newly user-defined grid.
Can anyone give some advice? Any help would be appreciated.
