WRF initializing WRF vs nesting

Hi all, I am interested to know if there should be an inherent difference in the simulation output between the two following cases: Case 1. A single 1 way nested run with gfsp25 initializing a WRF run with outer domain having 12km grid and inner nested domain with 4km grid. Case 2. First run gfsp25 ...

Problems interpolating SST --sfc file

Hello users, I am trying to use a high resolution source for SST in the Mediterranean (1km). The Grib file includes only one variable for the temperature and no mask of its own. When using this file I am getting temperature artifacts on coastlines only. I suspect that the problem is a masking issue ...

Re: Is there really benefit using --sfc rtgsst in the Mediterranean area?

The SST product data sheet: hort description: For the Mediterranean Sea- The CNR MED Sea Surface Temperature provides daily gap-free maps (L4) at 0.0625deg. x 0.0625deg. horizontal resolution over the Mediterranean Sea. The data are obtained from infra-red measurements collected by satellite radiome...

Re: Is there really benefit using --sfc rtgsst in the Mediterranean area?

More exploring.....

... they also have a 1km SST of the Med which is updated daily. This is specifically SST and is in Kelvin.
(sample in the dropbox).

Keen to know if it might be useful.

Thanks,
David

One needs to register and then download via their interface.
I sent you a PM with a dropbox link that has a sample sst file.

Re: Is there really benefit using --sfc rtgsst in the Mediterranean area?

Have you seen the data available from Mercator-Ocean (distributed by CMEMS)?

They have high resolution sea surface temperature (in centigrade) for the entire Mediterranean in netcdf format. I'm not sure if it is suitable for use in WRF initialization.

Is there really benefit using --sfc rtgsst in the Mediterranean area?

Hello all, I'm running forecasts in the Mediterranean area using dset gfsp25 for initialization and boundary conditions. I have also been using a static surface file - namely rtgsst It appears that there is more recent and better surface temperature data in the gfs dset files than in the rtgsst file...

Re: WRF benchmark problem

Hi Marian,
In Ubuntu 14.04 I have put those lines of code in '.bash_profile' in the UEMS user directory.
I'm not sure if version 16.04 uses the same file.
Hope it helped
