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

Glendale (Arizona), United States, Peoria (Arizona), United States and Goodyear lie in the same rainfall cell, so their rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
