sst_update

Hi, I'd like to know how to utilize SST data from a single data source. By this I mean the SST data is coming from the same grib file I'm getting the other initial and boundary data from. Instead of running ungrib twice, I include the SST variable within the main Vtable. This way I get the...

Hello, I want to do SST update using OISST data. I want to create an intermediate file using "netcdf-to-intermediate.f". The results depend on how I compile, but neither of them is the right time. Is there a problem with the compilation I tried? I would appreciate your response:) Below are the...

Hello, I am a student who is studying WRF. I succeeded in converting OISST data into intermediate data using netcdf-to-intermediate.f provided by ncar, but there is a time-varying problem. This problem did not occur when I converted OISST data for 2022, so why is it happening? I would...

Hi all, I'm in the process of updating SSTs in the WRF v3.8 model but I'm running into WPS issues when attempting to convert GLSEA SST data from netcdf to grib. I'm aware that there are similar posts on this forum however, after trying out a couple of different options, I am still running into...

Dear all, I have some questions about the sst_update: Which module does WRF call to read the auxinput4 file? How does WRF control the SST update interval? In which code file? Thank you for your attention.

Hello WRF community, I am running simulations with and without updating the sea surface temperature. When I plot the SST variable from the wrfout with and without SST updates, it has positive values over the continental region. I think it should be NaN or 0 values. Am I doing something wrong...

Hi Forum. I am trying to run a wrf model for 6 months using ERA5 re-analysis data. For which I have downloaded the SST and Sea-ice-cover data from Copernicus Climate Data Store | Copernicus Climate Data Store , along with 10m u-component of wind, 10m v-component of wind, 2m dewpoint...

Hi, I'm a student who just started learning the WRF model. I want to run the model using era5 data and OISST data. First, I downloaded the OISST data and made it into an SST.grb file with the same process as the attached picture. After that, I tried to run unrib.exe and metgrid.exe after link...

Hi, I am preparing a multi-year WRF simulation and need to update SST. I am not using an external SST dataset but want to update SST from ERA5 data, which is used as model input at the same time (I therefore did not run ungrib.exe twice to create separate ‘SST’ files for metgrid). ERA5 driving...

Hello guys! I am conducting forecasts with WRF for a period of 45 days and I am not sure if I should use the FDDA option for these forecasts. In this case, I am using 15 days of spin-up + 30 days (period of interest). The sea surface temperature I'm using from the CFSv2 itself with the option...

I am trying to run a simulation using sst_update=1 with two domains. There are no problems when starting the run in the usual way. But I have to drastically reduce the time step to get it through the first few minutes of the run. So, I thought I would try to delay the start of D2 by a few hours...
