Lambert conformal grid interpolation to finer resolution

[edsmitty]

Good Day,

I have run the WRF model on a single grid for a couple of years model time. I would like to take the soil moisture and soil temperature from this single 9 km grid and interpolate to the 3 km wrfinput file as a new lower boundary initial condition for a much shorter time integration. I am using a Lambert Conformal Conic projection. I would be grateful for any suggestions or assistance.

Thanks

Please clarify that Lambert Conformal Conic projection is applied to both your 9km an 3km domains.

I wonder whether the parameters used for the projection, i.e., truelat1, truelat2 (optional), stand_lon, ref_lat , ref_lon, are same for the 2 domains? If so, you can simply get a subset from your D01 data.

If the projection parameters are different, then you need to remap the data form D01 to D02. Please see whether the python script here can work for your case. Note that you may need to modify this script for your specific case.

Thanks so much!!

I have attached my namelist.wps for you to consider. I will first attempt subsetting the D01 the soil fields and also file away the code you passed along for future attempts. Thanks so much and any further advice is always appreciated, especially with respect to the the namelist.

This is a 6-domain nested case with the resolution varying from 9km to 40m. I guess you have run this case successfully?

Depending on where your new 3-km domain is located, I guess you can manage to obtain soil data based on your 9-km wrfout files. Please try and let us know if you have any issues.
