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 Cuautitlán) is explained once on the Cuautitlán year overview and on the Sources, method and limits page.

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