[Wrf-users] WPP and copygb

[teresa tiberi]

there all,

I will ask you about WPP (v.3) and copygb.

I'm using wrfpost-processor scripts to display NMM-WRF outputs.
they use copygb,because nmm output have staggered native e-grid and
must go through copygb to be interpolated to a regular non - staggered
grid.

wrfpost.F gives me copy_nav.txt (where it saves a Grid GDS of lambert
Conformal Grid similar in domain ad grid spacing to the one used to
run WRF model),
so during the script there are this rows:

read nav < ' copy_nav.txt '
export nav
../copygb.exe -xg"${nav}"  WRFPRS_..  out_...
grib2ctl.pl -verf out_.. > out_...ctl
gribmap -i out_...ctl
grads "plotting_script"

where in copy_nav.txt I find this value:
255 3 257 245  35666    4185 8   12098   5564   5610 0 64  42269  42269

where in ctl I find this value:
pdef 257 245 lcc 35.666000 4.185000 1 1 42.269000 42.269000 12.098000 5564 5610

I attach my T2m map and landsfc to show you my rotation problem: there
is a slight shift in the fields.

what can I manually change to have the right plot?

thanks in advance

Teresa

PS in the nmm wrf domain configuration I set this:

&geogrid
 parent_id         = 1,1,
 parent_grid_ratio = 1,3,
 i_parent_start    = 1,28,
 j_parent_start    = 1,32,
 e_we          = 106,130,
 e_sn          = 168,246,
 geog_data_res = '2m','30s',
 dx = 0.155701,
 dy = 0.151988,
 map_proj =  'rotated_ll',
 ref_lat   = 44,
 ref_lon   = 13.5,
 geog_data_path = '/home/condivisa/wrf/wrf/WPS/geo/geog',
 opt_geogrid_tbl_path =
'/home/condivisa/wrf/wrf/WPSV3/domains/mediterraneo_nest24/',
