I located the current RAP geo_em.d01.nc file and through some reverse engineering I've found this geo-figuration to give very similar results

&geogrid
dx = 0.1218329,
dy = 0.1218329,
e_we = 954,
e_sn = 835,
geog_data_res = 'default',
i_parent_start = 1,
j_parent_start = 1,
map_proj = 'lat-lon',
opt_geogrid_tbl_path = './',
parent_grid_ratio = 1,
parent_id = 1,
ref_lat = 54.,
ref_lon = -106.,
stand_lon = 106.,
truelat1 = ,
truelat2 = ,
POLE_LAT = 36.,
POLE_LON = 180.,
geog_data_path = './geog',
/

Through this I get identical values of dx and dy (=13545.08 meters), but the corner points are not bit-identical. Also, the value of "geog_data_res" is not 100% clear (I'm using V4.1 of WPS vs. 3.8 (?) in the operational RAP).

Best, Ólafur.
