ADAS assimilation run
Build model
First, choose a model tag to build. For this example, we choose GEOSadas-5_9_1_p7.
$ cvs co -P -r GEOSadas-5_9_1_p7 -d g591p8 GEOSadas-5_9
Not the module name GEOSadas-5_9. Unlike AGCM, all ADAS tags have a corresponding module.
$ cd g591p8/src $ ./parallel_build.csh
Setup experiment (Run fvsetup)
Run fvsetup from the bin directory (g591p8/Linux/bin) with the following options (default value chosen for ones not mentioned): [we choose the default value for the initial conditions (FVICS) as well]
AGCM Resolution? [b72] > C180 OGCM Resolution? [c34] > f34 EXPID? [u000_C180] > g591p8 OBSERVING SYSTEM CLASSES? > "ncep_prep_bufr"
Do Aerosol Analysis (y/n)? [y] > n
A pdf of the entire fvsetup session is provided here: File:Fvsetup session.pdf.
FVHOME
FVHOME is the home directory for fvDAS experiment. Resource files, restarts and system output will be stored under this directory. Usually it contains subdiretories:
ana/ first guess/analysis output anasa/ job script to run stand-alone analysis daotovs/ daotovs field output diag/ diagnostic field output etc/ listings and other odds & ends fcst/ forecast run directory fvInput/ process required inputs obs/ post-analysis ODS files prog/ prognostic field output recycle/ latest restart files rs/ restart files run/ resource files
$FVHOME/.FVROOT gives the location of the installation bin directory.
Some of these directories are stored in the archive. After completing the experiment, look in $ARCHIVE/g591p8 (where g591p8 is the experiment ID).
Run directory
$ cd $FVHOME/run
Data Assimilation experiment
$ cd $FVHOME/run $ qsub g5das.j
g5das creates a scratch directory $NOBACKUP/fvwork.xxxx and runs the experiment there. After the initial setup, GSIsa.x is run with output written to ana.log followed by GEOSgcm.x which writes its output to stdout and fvpsas.log.
