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

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