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 Lomas de Zamora) is explained once on the Lomas de Zamora year overview and on the Sources, method and limits page.

Laferrere, Isidro Casanova and Ezeiza lie in the same rainfall cell, so their rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
