In Response To: Updated namelist.wps for RAP? (Ólafur Rögnvaldsson)

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.
