copygb grids

Postby soonertiger2012 » Tue Jan 14, 2014 4:21 pm

I am attempting to run copygb.exe and have a script that I "inherited" from someone else in my group that has this line in it:

./copygb.exe -xg"255 0 204 214 -3707 99093 136 48321 159303 296 244 64" WRFPRS_d01.00 wrfprs_d01.00

I am trying to decipher what all these numbers mean (something to do with the grid/map projection I believe) since I need to run copygb for another case. The documentation I've found is spotty at best trying to explain these different numbers. Any assistance on figuring out these numbers (and how to get them for a different case) would be greatly appreciated! :)

Okay, I now know where these numbers come from, but I'm having trouble setting it up with a Mercator grid (I believe this is possible, but correct me if I'm wrong).

Here is what I have: ./copygb.exe -xg"255 1 589 299 1928 -167445 8 64652 -2555 30000 0 64 27000 27000" postprd/WRFPRS_d01.000 postprd/grib_files/wrf.control.irene.2011082300.f00000

Whenever I use ./wgrib -V [file] to look at the map projections of the input and output files, everything looks okay, except for the resolution (27000m x 27000m). It is showing up as 0 x 0 in the new grib files.

Does anyone know what the format is supposed to be for Mercator projections? I've been trying to use the following two links:
