Amending altitude in a climate file

Hi,

The .try dwd climate file I'm using has the altitude set to 0 masl. is this going to give unrealistic wind driven rain results?

Thanks

Dear Dan,

the altitude is only used to calculate a yearly constant air pressure, if a climate file contains no column for the air pressure, so this should not be a problem as the try climate has a column for the air pressure.

The air pressure is used to calculate the water vapor permeability of air.
