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 Gimpo-si) is explained once on the Gimpo-si year overview and on the Sources, method and limits page.

Incheon, Bucheon-si and Gwangmyeong lie in the same rainfall cell, so their rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
