UofU forked model components:

• AWSM
• SMRF
• weather_forecast_retrieval

All other model components are in the latest released versions as of 2022-08-01 and available on the ARS GitHub.

Branches on the UofU forks:

• ERW_wy_comparsion_202109 Code as used with GMD submission
• ERW_solar_albedo Current development

General model execution:

• Download HRRR; script: download_hrrr.sh
• Extract 6th-hour forecast; script: extract_precip.sh
• Run Katana; script: katana.slurm
• Run first day of water year: script: run_first_day.sh
• Run model: script: iSnobal.slurm
• Compact SMRF output for faster analysis; script: iSnobal-SMRF.slurm
• Use SMRF linker for possible model re-runs: script: SMRF_linker.sh

Steps in current development:

For all runs

• Execute base line model with ERW_wy_comparsion_202109 branch
• Calculate topographic shading and extract DSWRF from HRRR:

~/isnoda/scripts/smeshr/dswrf_for_topo.sh \
  ~/project-data/iSnobal/ERW/topo/basin_setup/topo.nc \
  "hrrr.202206*" \
  "hrrr.t*f06.grib2" \
  ~/skiles-group1/SMESHR/DSWRF/wy2022/ERW;

• Extract TCDC from HRRR; generate cloud_factor.nc as model input

~/isnoda/scripts/smeshr/tcdc_for_topo.sh \
  ~/project-data/iSnobal/ERW/topo/basin_setup/topo.nc \
  "hrrr.20220[456]*" "hrrr.t*f06.grib2" \
  ~/skiles-group1/SMESHR/TCDC/wy2022/ERW_ \
  2022 \
  "6 7 8" \
  ~/skiles-group1/SMESHR/TCDC_ERW/wy2022;

For SMRF albedo

• Generate net_solar.nc from HRRR DSWRF and SMRF albedo as model input

~/isnoda/scripts/smeshr/net_dswrf_for_topo_SMRF.sh \
  2022 \
  ~/skiles-group1/SMESHR/DSWRF/wy2022/ERW_hrrr \
  ~/skiles-group1/erw_isnobal/wy2022/erw \
  ~/skiles-group1/SMESHR/net_HRRR/wy2022;

For MODIS albedo

• Extract albedo from MODIS; prepare file cropped to model domain
• Generate net_solar.nc from HRRR DSWRF and MODIS albedo

Final steps for both (SMRF and MODIS)

• Copy base model run output folder structure

find run* -type d -exec mkdir -p ../erw_hrrr_solar/{} \;

• Link the generated net_solar.nc and cloud_factor.nc to the output location for each day (runYYYYMMDD); script: HRRR_linker.sh

/uufs/chpc.utah.edu/common/home/u1135435/isnoda/scripts/smeshr/HRRR_linker.sh "run202207*" ~/skiles-group1/SMESHR/net_HRRR/wy2022/net_dswrf.MST net_solar.nc

• Execute model with ERW_solar_albedo branch
