Source for SST Data (preferably GRIB2) to Combine with GDAS for Typhoon Experiments in WRF/WPS

[junius.Wang]

Hi everyone,

I’m running tropical-cyclone simulations with WRF using GDAS analysis fields (0.25°), but—as many of you have pointed out before—GDAS does not include sea-surface temperature. The missing SST is degrading my typhoon intensity results, so I need an additional SST field that WPS can ingest easily.

What I’ve tried so far
• Downloaded the NOAA OISST v2.1 data from
NOAA 0.25-degree Daily Optimum Interpolation Sea Surface Temperature (OISST), Version 2.1
(specifically the directory …/sea-surface-temperature-optimum-interpolation/v2.1/access/avhrr).
• The files are daily NetCDF (*.nc) and require extra steps (ungrib or metgrid don’t read them directly).

What I’m looking for

1. A ready-to-use SST product in GRIB2 (or any format directly supported by ungrib.exe).
2. Alternatively, a reliable workflow or tool to convert NetCDF SST to GRIB2/WPS format without losing metadata needed by ungrib.

Does anyone know a download site or an established approach that works well with GDAS initial/boundary conditions? Any pointer—NCEP products, Hi-res RTG, or scripts you’ve used—would be greatly appreciated.

Thanks a lot!

Best regards,
junius.Wang

I am sorry that I don't have such information.

Hope someone in the community may know where to get high-quality SST ...
