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 Ciudad López Mateos) is explained once on the Ciudad López Mateos year overview and on the Sources, method and limits page.

Mexico City, Naucalpan de Juárez and Miguel Hidalgo lie in the same rainfall cell, so their rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
