Lat/Lon incorrect in polar stereographic grid

[moab360]

Getting around to doing more testing with GribApi. The latest version still does not read Lat/Lon correctly from grib files. (comparing to wgrib2)

The bottom left of the grid has the correct lat/lon, but after that it appears they are incorrect

wgrib2 shows the bottom right
wgrib2.exe cloud_003 -s -ijlat 935 1
1:0:d=2017110700:TCDC:surface:3 hour fcst::(935,1),lon=282.212082,lat=17.342726,val=22

GribApi shows the bottom right of the grid to be at
lat=19.4115478973818, lon=278.646091411221

The gribs I'm using come from the Canadian Meteorological Center. Examples can be found here - http://dd.weather.gc.ca/model_gem_regional/10km/grib2/00/003/. Doesn't matter which you chose in that folder since they are all on the same grid.

Not sure how much control you have over the lat/lon locations coming out of the native portion of this solution, but figured I'd let you know it doesn't work with polar stereographic

I should note, this is using GribApi 1.0.0-beta4

This may have been resolved in ecCodes 2.5.0
https://software.ecmwf.int/wiki/display/ECC/ecCodes+version+2.5.0+released

GribApi.NET 1.0.0-beta4 uses ecCodes 2.4.1

Looks like the following bug got fixed in ecCodes 2.5.0
[ECC-529] - grib_get_data for polar stereographic gets wrong lat and long
I don't have permissions to read more about the bug, but potentially this is the fix.

Is it possible for me to patch?
