Questions

• How do I run the model diagnostics packages?

Objectives

Some requirements for the diagnostics packages

Each component diagnostics package has minimum requirements for how much data must be available to run them:

• Ocean: 12months
• Atmosphere, Land: 14 months
• Ice: 24 months

Some other requirements:

• Only complete years can be analyzed by the packages.
• There must be an additional Dec before the 1st analyzed year or an additional Jan and Feb after the last analyzed year.
• If you have 4 complete years, you must set the first year to analyze to 1 and the last year to 3 or the first year to 2 and the last year to 4.

Run a Diagnostics Package

Select and run a diagnostics package of interest to you:

Atmosphere Diagnostics Package

Edit the settings for the env_diags_atm.xml file using pp_config

./pp_config --set ATMDIAG_OUTPUT_ROOT_PATH=/glade/scratch/cstan/diagnostics-output/atm
./pp_config --set ATMDIAG_test_first_yr=1
./pp_config --set ATMDIAG_test_nyrs=3

Run the monthly climatologies

qsub -A UGMU0041 atm_averages

You can monitor your job status using qstat -u Check the log file in logs to make sure everything ran ok. This should run relatively quickly (only a few minutes)

Once the averages are done, you can submit the diagnostics script:

qsub -A UGMU0041 atm_diagnostics

This will also run relatively quickly (few minutes).
Once it is done, you can go to the location of the diagnostics and look at the output via a webpage:

cd glade/scratch/cstan/diagnostics-output/atm/diag/run.2-obs.1_3
firefox index.html &

It may be slow for your web browser window to launch and display depending on your bandwidth.

Land Diagnostics Package

Edit the settings for the env_diags_land.xml file using pp_config

./pp_config --set LNDDIAG_OUTPUT_ROOT_PATH=/glade/scratch/cstan/diagnostics-output/lnd
./pp_config --set LNDDIAG_clim_first_yr_1=1
./pp_config --set LNDDIAG_clim_num_yrs_1=3
./pp_config --set LNDDIAG_trends_first_yr_1=1
./pp_config --set LNDDIAG_trends_num_yrs_1=3

Run the monthly climatologies

qsub -A UGMU0041 lnd_averages

You can monitor your job status using qstat -u Check the log file in logs to make sure everything ran ok. This should run relatively quickly (only a few minutes)

Once the averages are done, you can submit the diagnostics script:

qsub -A UGMU0041 lnd_diagnostics

This will also run relatively quickly (few minutes). Once it is done, you can go to the location of the diagnostics and look at the output via a webpage:

cd /glade/scratch/cstan/diagnostics-output/lnd/diag/run.2-obs.1_3
firefox setsIndex.html &

It may be slow for your web browser window to launch and display depending on your bandwidth.

./pp_config --set OCNDIAG_WORKDIR=/glade/scratch/cstan/diagnostics-output/ocn/diag/run.2.\$OCNDIAG_YEAR0.\$OCNDIAG_YEAR1

Run the monthly climatologies

qsub -A UGMU0041 ocn_averages

You can monitor your job status using qstat -u Check the log file in logs to make sure everything ran ok. This should run relatively quickly (only a few minutes)

Once the averages are done, you can submit the diagnostics script:

qsub -A UGMU0041 ocn_diagnostics

Ice Diagnostics Package

Edit the settings for the env_diags_ic.xml file using pp_config

./pp_config --set ICEDIAG_BEGYR_CONT=1
./pp_config --set ICEDIAG_ENDYR_CONT=3
./pp_config --set ICEDIAG_YRS_TO_AVG=3
./pp_config --set ICEDIAG_PATH_CLIMO_CONT=/glade/scratch/cstan/diagnostics-output/ice/climo/\$ICEDIAG_CASE_TO_CONT/
./pp_config --set ICEDIAG_DIAG_ROOT=/glade/scratch/cstan/diagnostics-output/ice/diag/\$ICEDIAG_CASE_TO_CONT/

Run the monthly climatologies

qsub -A UGMU0041 ice_averages

You can monitor your job status using qstat -u Check the log file in logs to make sure everything ran ok. This should run relatively quickly (only a few minutes)

Once the averages are done, you can submit the diagnostics script:

Try the CVDP

Our runs are not long enough to run the CVDP, but you can test it on an existing long simulation, the CESM Large Ensemble.

On Cheyenne, we need to get an analysis node to Casper

execdav --account=UGMU0041
cd ~/scripts/CVDP

Open the file namelist using your preferred text editor

The format of the file is: Run Name | Path to all data for a simulatoin | Analysis start year | Analysis end year

Modify the rows so that the analysis start and end years are 1979 and 2015.

Open up the file driver.ncl using your preferred text editor

On line 7: replace user with your username On line 19: change False to True to output calculations in nceCDF

Run the CVDP by typing

ncl driver.ncl

It will take ~20 minutes. Once it is complete, go to the output directory and open a firefox window

cd /glade/scatch/cstan/CVDP
firefox index.html&
