Running ADAS

First, we choose a DAS run to simulate. For a list of various runs

 $ ls ~dao_ops

on NCCS discover. As an example, we choose the run 'e572p5_fp'.

1. Checkout and build the model:

Check with Joe Stassi for model tag and module name.

 $ cvs co -r GEOSadas-5_7_2_p5_m1 GEOSadas-5_7
 $ cd GEOSadas/src
 $ source g5_modules
 $ gmake install

Or, one can checkout the corresponding AGCM model Fortuna-2_5_p6 (module Fortuna) and build it.

2. Experiment setup:

To simulate a forecast run we can use gcm_setup to setup our experiment (instead of fvsetup). Run ./gcm_setup and provide the required answers

 $ cd Applications/GEOSgcm_App/
 $ ./gcm_setup

Cubed-sphere was not fully implemented in this model. Choose Lat/Lon with resolution 1152x721x72 for the 'e'-run. The other options are

 GOCART: yes
 GOCART Emission Files to use: OPS
 AERO_PROVIDER: GOCART
 HISTORY: Current

3. AGCM.rc, CAP.rc, HISTORY.rc

Edit these files to match with the corresponding .tmpl files in

 ~dao_ops/e572p5_fp/run

4. gcm_run.j

Ensure that the correct boundary datasets are linked to. Compare the links in this file to that of

 ~dao_ops/e572p5_fp/run/lnbcs

5. RC files

Copy the .rc files over

 $ find ~dao_ops/e572p5_fp/run -name "*.rc" -exec cp {} /path/to/home/dir/RC \;

6. restart files

Locate the dir containing restarts by querying FVARCH in FVDAS_Run_Config

 $ grep FVARCH ~dao_ops/e572p5_fp/run/FVDAS_Run_Config
   setenv FVARCH   /archive/u/gmao_ops/GEOS-5.7.2/${ATAG}/ #include trailing colon

 $ grep ATAG ~dao_ops/e572p5_fp/run/FVDAS_Run_Config
   setenv ATAG    GEOSadas-5_7_2_p5_m1
   setenv ATAG    $GTAG
   setenv FVARCH   /archive/u/gmao_ops/GEOS-5.7.2/${ATAG}/ #include trailing colon

Pick a date and time: say 2012/05/15, 21z

 $ cd /archive/u/gmao_ops/GEOS-5.7.2/GEOSadas-5_7_2_p5_m1/e572p5_fp/rs/Y2012/M05
 $ ls *_rst.20120515_21z.bin

Copy these files over from ARCHIVE to experiment directory.

7. Run job

 $ qsub gcm_run.j
