[Met_help] [rt.rap.ucar.edu #66308] History for LCC versus LCCR grid with copygb?

[John Halley Gotway via RT]

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

Greetings:

I am having issues understanding what is the actual difference between a
LCC and a LCCR grid.

when running ARWpost, I get in the Grads ctl file:

title  OUTPUT FROM WRF V3.4.1 MODEL
pdef 1199 799 lcc  39.000  -98.000  600.000  400.000  60.00000  30.00000
-98.00000   4000.000   4000.000
xdef 3904 linear -133.17477   0.01801802
ydef 1806 linear   21.46067   0.01801802

when running copygb as follows (using parameters from ncdump -h that I
believed were correct ):

../bin/copygb.exe -xg"255 3 1199 799 21641 -120450 136 -98000 4000 4000 0
64 60000 30000"   file

I get in the grads ctl file:

pdef 1199 799 lccr 21.641000 -120.450000 1 1 60.000000 30.000000 -98.000000
4000 4000
xdef 1199 linear -120.450000 0.0391211777253789
ydef 799 linear 21.641000 0.0363636363636364

Any clues of what I am doing wrong with copygb ? The documentation on the
latter is quite obscure and hard to find: i.e., There is absolutely no
succinct comprehensive Doc file explaining all the options line by line for
all the possible grid projections. I could only find some random
information on tutorial PPT files.

Cheers and best,

Alex,

I see that you have questions about ARWpost and copygb.  Support for
ARWpost and copygb are provided through wrfhelp.  While we do
sometimes answer questions about copygb through met_help when they
relate to verification, I'd suggest sending this one to
wrfhelp at ucar.edu.

Hopefully they'll be able to help you out.

Thanks,
John Halley Gotway
