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

Re: UEMS CPU suggestion

Hi, My experience is that the first priority is the number of physical cores 10 is much better than 6 even with a somewhat different cpu speed. Second speed issue is often related to the RAM slot population and bios settings. The CPU to memory speed is important. The CPU caches also come into play h...

Re: UEMS vs WRFEMS run time

I have found that in UEMS the thread handling appears to be better than with EMS and the rule that MAX_CPUS - 1 should be used is not necessary correct. With an Intel machine (dual Xeon X5650) with a total of 12 cores setting the number of cpus to 12 gives better times than 11. Also in a cluster of ...

Re: some fields like APCPsfc, GUST10m, TCDCclm - problem

Hello Ivan,

If you enable DFI=3 some of the variables for T=0 will show values including Gust.
I got this tip from Robert :-).
