WRFDA 3.8.1
Published:
Run real cases
Install WRFDA directory is $WRFDA
my working directory is $WRKDIR/wrfda
A. link files to $WRKDIR/be.dat:
cp $DAT_DIR/namelist.input.3dvar ./namelist.input
ln -sf $WRFDA/run/LANDUSE.TBL .
ln -sf $WRFDA/var/da/da_wrfvar.exe .
ln -sf $WRKDIR/obs/obs_gts_2017-06-12_12:00:00.3DVAR ./ob.ascii
ln -sf $WRKDIR/wrf/wrfinput_d01 ./fg
The above files are the ouputs of the following processes:
fg=wrfinput_d01 : Run WPS(NMM) (or ARW)
ob.ascii : MADIS to little_r or WRFDA – LIITLE_R
radar.ascii : WRFDA (Py-Art and Radar)
