How is SST computed in the WRF model? (RESOLVED)

Post by Liliputian_123 » Wed May 26, 2021 4:10 am

Dear WRF-experts,

I am running a simulation using GFS forecast data.
I cant see a SST variable in the input files (see attached output file).

On the other hand, in the ARWpost ctl file there is SST output.

So I wonder how does WRF calculate the SST? Where can I find information on this?

I'll appreciate any help!

Hi Lyndz,
If you do not have specific SST data available, the model uses the values for skin temperature (SKINTEMP in WPS, TSK in WRF) to derive SST. I believe this takes place in the dyn_em/module_initialize_real.F file.
NCAR/MMM
