# Part I: WRF
## Review of WRF framework
## Executables
## Install WPS and WRF
`cd ~wrfhelp`
```
BATCH_SCRIPTS_CHEYENNE
intel
PRE_COMPILED_CHEYENNE
SOURCE_CODE
UNGRIB_LIBRARIES
WPS_GEOG
```
## Get compiled code
```yaml
cd /glade/scratch/cxiao
mkdir WRFTest
cd WRFTest
mkdir WPS
mkdir WRFV3
cp -r ~wrfhelp/PRE_COMPILED_CHEYENNE/WPSV3.7.1_intel_serial_large-file/* WPS/
cp ~wrfhelp/PRE_COMPILED_CHEYENNE/WRFV3.7.1_intel_dmpar_large-file/test/em_real/* WRFV3/
```
## WPS: `namelist.wps`
`cd WPS`
* Replace the example with my Lake Champlain `namelist.wps`
+ `cp ~cxiao/WORK/Champlain/WPS/namelist.wps .`
* Check (adjust) model domain
+ `module load ncl`
+ `ncl util/plotgrids_new.ncl`
## WPS: run executables
* Generate static terrain file
+ `./geogrid.exe`
* Extract forcing file
+ Forcing (e.g. NARR) in GRIB format
- `./link_grib.csh ~cxiao/DATA/20110101/*`
+ Vtable
- `ln -sf ungrib/Variable_Tables/Vtable.NARR Vtable`
+ ungrib
- `./ungrib.exe`
* Regrid forcing file in **parallel**
+ `cp ~cxiao/WORK/Champlain/WPS/runmetgrid.sh .`
+ `qsub runmetgrid.sh`
## WRF: `namelist.input`
`cd ../WRFV3`
* Replace the example with my Lake Champlain `namelist.input`
+ `cp ~cxiao/WORK/Champlain/WRF/namelist.input .`
* Job submission scripts
+ `cp ~cxiao/WORK/Champlain/WRF/runreal.sh .`
+ `cp ~cxiao/WORK/Champlain/WRF/runwrf.sh .`
* Submit jobs
+ `qsub runreal.sh`
+ `qsub runwrf.sh`
# Part II: WRF-Hydro
## Define domain
* WPS `geogrid.exe`
+ geo_em.d01.nc
* WRF `real.exe`
+ wrfinput.nc
## Hydrofabic
```
* WRF-Hydro ArcGIS Toolbox
+ https://github.com/NCAR/wrf_hydro_arcgis_preprocessor

## Generate Forcing
* NLDAS2 (13 km) ----> WRF-Hydro land component (1 km)
* NCL with Earth System Modeling Framework (ESMF) `ESMF_regrid`
