What is the spatial resolution of the climate change projections produced by the CCSM-3?

The spatial resolution of CCSM-3 climate change projections is approximately 1.4 x 1.4 degrees. However, the model outputs are generated on an irregular grid. The longitude range can be exactly specified - the center of the first grid box is at 0E and the spacing is precisely 1.40625°. The latitudes, however, vary in spacing from 1.389° to 1.400767°.
