For example, today, 19th January, GFS only has 18th January SST filehttp://www.ftp.ncep.noaa.gov/data/nccf/com/gfs/prod/sst.20160118/So I would just like to use that file for my daily 4 runs. I repeat that I've already created my regular ungrib files for GFS, so the only change between GFS ungrib and SST ungrib is the SST word in PREFIX (notice that I've already linked the SST vtable and used link....csh

ok how do you set your namelist.wps
Could I have a look at your namelist.wps settings?

Hi, I've already done that, but it goes search 03h sst data files every 3 hours :(
What's wrong?

Thanks,Giacomo

I am not sure about your question but I think when you do the ungrib process,  you can set the sst data to be 3 or 6hourly

Hi everybody, I'm currently using WRF-NMM for my 2-km domain.
I download 3h grib2-files from GFS, and generate WPS files each 3 hours.I would also like to use SST data for my WRF simulations, but the problem is that SST files are only daily, and they are released the day after. For example if I want this:
START= 15-January-2015_12ZEND= 17-January-2015_12Zwith an INTERVAL of 3 hours and PREFIX=SST, even after correctly linking the Vtable and link_grib.csh, WPS-UNGRIB searches for 15-January 2015 12Z, but the only SST file is for 14 January!
If I put 14 January 00Z as start date, then it would search for 03Z!

How could I do?

Thanks in advance!
