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

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