Thus, the rotated pole has the correct coordinates (140 deg lon, 45 deg lat) since 140+36=180 and 45+45=90. If you take a look at rlat and rlon, that I printed with ncl_filedump, you can clearly see that in the rotated framework lat and lon both start from -10 (-9.962) and -20 degrees (360-340). <div
