Not enough soil temperature data for Noah LSM scheme.

[jchiquetto]

Dear users,

I am using WRF v. 4.4 and trying to run a small simulation using GFS data.

However, I am getting this error after I run real.exe:
FATAL CALLED FROM FILE: <stdin> LINE: 2792 Not enough soil temperature data for Noah LSM scheme.

Things seem ok during the other preprocessing stages (WPS V 4.5), although there is a flag when completing metgrid:
The following floating-point exceptions are signalling: IEEE_OVERFLOW_FLAG IEEE_UNDERFLOW_FLAG IEEE_DENORMAL (not sure if this is relevant?)

I am using GFS data from this source:

Grib Filter gfs_0p25

However, I am downloading only 1 of the 384 options in the "Available Files" list. I think I might be missing some data, as soil temperature, for example.
I tried downloading for a specific lat/lon subset, and also with global data.

I just wanted to make a quick run to confirm that the model is running ok. Is it possible to do so with a GFS dataset that is simple and easy to obtain manually (I can't use ftp)? If so, where can I find it?

Sorry if this is too basic, I am runnin WRF again after many years and stumbling on the initial steps.

Thanks for your help!
Julio

Hi Julio,
I would recommend trying to obtain GFS data from NCAR RDA. Each of those files should contain the full set of input variables needed to run WRF. You will need to register for an account, but it should be quick and easy.

Things seem ok during the other preprocessing stages (WPS V 4.5), although there is a flag when completing metgrid:
The following floating-point exceptions are signalling: IEEE_OVERFLOW_FLAG IEEE_UNDERFLOW_FLAG IEEE_DENORMAL (not sure if this is relevant?)

Regarding this floating-point exceptions message, you can ignore that.

if you have the bandwidth you can download the total file, which has everything, including more than what is needed. WRF will only ingest what it can.
