hi
I use the same dataset to plot the Lambert Conformal(maskd) and Lambert Conformal(native)
See attach file(native.gif and mask.gif)
The plot "native.gif " is correct but when i plot "mask.gif" will get the warning message bellow
(0) mask_lambert_conformal : warning : you are using a projection other
(0) than LambertConformal. Unexpected result will likely occur.
and you can see the plot "mask.gif" contour is a little shift to right side
below is the scripts :
begin
f = addfile("mm5.nc","r")
t = f->t(0,0,:,:)
wks = gsn_open_wks("ps","mask")
gsn_define_colormap(wks,"gui_default")
res = True
res@mpGridAndLimbOn = True
res@mpGridLatSpacingF = 3.
res@mpGridLonSpacingF = 4.
res@mpProjection = "LambertConformal"
res@gsnMaximize = True
res@mpMinLatF = f@lat00
res@mpMinLonF = f@lon00
res@mpMaxLatF = f@latNxNy
res@mpMaxLonF = f@lonNxNy
res@cnFillOn = True
res@gsnAddCyclic = False
i = NhlNewColor(wks,0.8,0.8,0.8)
res@gsnSpreadColors = True
res@gsnSpreadColorStart = 4
res@gsnSpreadColorEnd = -2
res@tfDoNDCOverlay = True
res@gsnMaskLambertConformal = True
plot = gsn_csm_contour_map(wks,t,res)
end
Thank you
