[NARCCAP-discuss] epsg value for CRCM-cgcm3 model

[Oleksandr Huziy]

Hi Jianhua:

It is rotated lat/lon, the proj4string is smth like this:
+o_proj=longlat +lon_0=<your true pole longitude in this crs>-180
+o_lat_p=<your true pole latitude> +R=6370997.0 +proj=ob_tran +units=m
+o_lon_p=<longitude of the rotated pole in the true lat/lon>


those things in <> could be found in the header of the netcdf file.

Can you show me your plotting code? I've never done it in R, though tried,
and abandoned, seems to complicated))

It would be great to have a working example code with data attached to it
(just one field for one time step)

thanks

Cheers
