try the mpasout file in order to use 2mT/10m wind for data assimilation #130

Open guoqing-noaa opened 2 months ago

guoqing-noaa commented 2 months ago

The current MPAS model outputs diag.nc, history.nc and restart.nc files

From MPAS v8.2 and MPASJEDI v3.0, we can use mpasout files to do data assimilation and warm start a new forecast.

We need to include 2mT/10 wind diagnostics in the mpasout file.

@spanNOAA is testing this. The test codes can be found here: https://github.com/rrfsx/mpas-bundle

@spanNOAA My cloned code is here: /mnt/lfs5/BMC/wrfruc/gge/RDASApp/mpas-bundle

The pre-built executables are here: /mnt/lfs5/BMC/wrfruc/gge/RDASApp/mpas-build

Once everything works well, we will update the corresponding RDASAPP submodules.

Any update? Does it need to change code or just edit yaml to use 2mT/10m from background?

We need to modify the JEDI c++ codes to achieve this. Sijie started this work before his leave and made some changes. It is not ready yet. He will be back in Sept. 23rd,
