Hi Sylvia,
thanks a lot to point me to the right pages. I think I have to get much
more accustomed to your page. I have now printed the longitude/latitude
lines on the plots, but still have some problems.
The problem with the tickmarks: I don't want longitude tickmarks, but of
my native grid, to find cell 67x98 easier.
But neither the res@pmTickMarkDisplayMode = "Always" (not for grid, not
for longitude), and even setting tmXB to explicit, labelsON and setting
explicit values as described in you link, doesn't help.
I just tried to plot
http://www.cgd.ucar.edu/csm/support/CSM_Graphics/native.shtml
native_4.ncl. I included my data and added explicit values for
res@mpLambertParallel1F = 30.
res@mpLambertParallel2F = 55.
res@mpLambertMeridianF = 45.
res@mpLeftCornerLatF = 86.31 ; left lower corner
res@mpLeftCornerLonF = -133.31 ; 0.5 111.5
res@mpRightCornerLatF = 20.21 ; right upper corner
res@mpRightCornerLonF = 16.68 ; 132.5 0.5
I didn't get ticks. I get some warnings, maybe they
are connected to the problem:

About the projection not perfectly lining up: I have a very explicit
explanation of the grid: Oh, sorry, I just wanted to send you the
grid-explanation, when I figured out, that it says -32degrees. I don't
know, where I got the -30degrees from. (And I worked on it more than a
half day.) So, the projection seems to be perfect, it was my problem.
