(RESOLVED) Initializing nested grids with different input datasets

[lesnow93]

Dear WPS forum,

I'm looking to initialize a concurrent, one-way nested grid run of WRF with different land surface model (LSM) fields for the various nests.
For example, I'd like to initialize the LSM fields with NAM or GFS on d01, and then use a custom, higher-res LSM initialization on d02 and d03.

How best can this be accomplished in WPS/metgrid such that I can make a WRF simulation with these different initialization strategies without requiring the use of ndown and separate simulations on each nested grid?

Thanks in advance for the insight!

Sincerely,

Jonathan,

You probably can try to replace the original soil data in d02 and d03 by your own high-res data. Please see the code here:

You can use the above utility or NCL or any other options you are familiar with to rewrite the soil data.
