RTG SST Product Discontinued, Replacements?
It appears that the RTG SST product has been discontinued. Is there any replacement suggested for the WRF Community? Is this something that I can contribute by adding another product (e.g. OISST) to WPS?
Thanks!

Another contender...
MUR SST (JPL): 1-June 2002 to Present, Daily Output, ~1km Resolution
OISST (NOAA NCEI): 1-Jan 1981 to Present, Daily Output, 0.25º Resolution
@jbzambon Are these GRIB data? Do we need a new Vtable for these? How do you plan to contribute?
Unfortunately, these are NetCDF data and not GRIB. I have a simple python utility to convert the NetCDF to WPS Intermediate Files, bypassing ungrib.exe. I can port it to Fortran. I'm just reaching out to see if there's interest, and if so what SST files people are going to use so I can code the utility appropriately.
Thanks!
Hi jbzambon, MUR SST is probably the best replacement for rtg_sst feed to WRF. Yes, the interest in utilising it with regional WRF coastal applications do exist. Could you please share those python script you mentioned and the Fortran implementations - when its ready?
Hope these utilities would allow users to convert a subset of mur_sst files into WPS files to use with metgrid.exe or be used as a template to built their own.
Thanks !
I have posted a Fortran program to convert MUR SST (and any of the other GHRSST products hosted at JPL's PODAAC) to WPS Intermediate format. You'll also need my utility to interpolate WPS Intermediate files. https://github.com/bbrashers/WPS-interp-intermediate https://github.com/bbrashers/WPS-interp-intermediate
@bbrashers Thank you very much for making the code available. We may offer it to our users if asked.
Sorry I paste incorrectly, and even though it's easy to find, just for completeness the link is https://github.com/bbrashers/WPS-ghrsst-to-intermediate
And let me know if this sort of thread should really be on the WRF Forum.
@bbrashers At the moment, the appropriate Forum area you could post is under 'Miscellaneous/General Questions' and then 'Code Contributions'. The idea here is that we have a place to point to the interested users. Thanks.
@jbzambon If you are interested, you can post your python script under the code contribution area too. Thanks for contributing to the community!
@bbrashers - Thank you very much for sharing you FORTRAN code at https://github.com/bbrashers/WPS-ghrsst-to-intermediate. It works excellent with ghrsst subsets, I was need only to extend slightly the sub-setting selection beyond the max, min limits in geo_em.d01.nc. Also in csh scripts I added the "./" prefix before ./add_time and other calls to exe, such as ./ghrsst-to-intermediate and ./interp-intermediate in CentOS7.
I put in a 0.5-degree buffer around the geo_em.d01.nc lat-lon range. Did you need a bit more? I can change the code, if you have come across a case where 0.5° was not enough.
(In my environment I have add_time in /usr/local/bin, and have added ./ to regular user’s $PATH, which is why I didn’t put in ./ prefixes.)
