Sources, method and limits

How these numbers are made (what the highs, lows and rain days mean, the sources and the model cell used for Prosperidad) is explained once on the Prosperidad year overview and on the Sources, method and limits page.

San Francisco, Philippines lies in the same rainfall cell, so its rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
