(RESOLVED) Why the CORDEX domain is used?

[littleho_song]

I have some general question on the projection that the CORDEX project is using:
e_we = 126
e_sn = 123
dx = 0.44,
dy = 0.44,
map_proj = 'lat-lon',
ref_lat = 60.21,
ref_lon = -44.14,
ref_x = 11,
ref_y = 113,
stand_lon = -18,
pole_lat = 39.25,
pole_lon = -162,

The above is what is recommended for the cordex project. My question is that isn't this distorting more than a LAMBERT projection?

Although I'm not really familiar with the CORDEX project, I can offer that the rotated lat-lon projection can provide very little map scale distortion over large geographic areas. So, depending on the parameters of the Lambert projection, it may be possible to obtain less distortion using a rotated lat-lon projection.

Sorry, is there a way to check which projection has the most distortion? I wonder if by comparing the maximum map factor would be enough.

map factor is the variable that can tell how severe the distortion could be.
