2.0 : WRF netcdf / CTL

Hi everybody,
thank you for providing GraDS 2.0, it's really cool to open NetCDF
files directly.
However, I have a problem to configure the CTL file correctly for the
lambert projection (I think PDEF is the issue).
Here is my CTL file :
dset ^file.nc
dtype netcdf
undef -888
TITLE WRF Output Grid: Time, bottom_top, south_north, west_east
pdef 48 46 LCCR 46.6 1.1 24.5 23.5 46.6 46.6 1.1 27000 27000
xdef 48 linear -6.422363 0.319
ydef 46 linear 40.87268 0.24
zdef 27 linear 1 1
tdef 2000 linear 29jan2008 30mn
vars 1
LANDMASK=>l 0 t,y,x landmask
endvars
Here is my namelist.wps to configure the area of interest for my WRF model :
&geogrid
parent_id = 1,
parent_grid_ratio = 1,
i_parent_start = 1,
j_parent_start = 1,
e_we = 49,
e_sn = 47,
geog_data_res = '2m',
dx = 27000,
dy = 27000,
map_proj = 'lambert',
ref_lat = 46.6,
ref_lon = 1.1,
truelat1 = 46.6,
truelat2 = 46.6,
stand_lon = 1.1,
geog_data_path = '/mnt/scratch/meteo/geog',
/
ref_x = 24.5,
ref_y = 23.5,
Unfortunately, the landmask from the WRF output does not coincide with
the Grads Map - a serious problem for me, evidently ! Please see the
image illustrating my problem (it's only 20KB).
Could anybody tell me if I am in the wrong direction ?
I would appreciate your help. It is so hard to find someone with some
WRF and GrADS experience to talk to.
Have a nice day !
Patrick
