| Oct 3, 2018 at 22:44 | comment | added | Get Spatial | Jon, good question. It was 5 years ago, and my guess now, from looking at it is that I put a decimal wrong and rounded or something. I almost realized this as I mentioned that my final area numbers looked small, but obviously didn’t follow that through. | |

Add detail to answer

| Apr 25, 2013 at 3:23 | comment | added | whuber | I find the initial calculations misleading: the cell size definitely is not 120 meters, except perhaps near the Equator--which doesn't include much of Asia. :-) The cells are essentially rectangular, not square, and their aspect ratios vary across the map with latitude. | |
