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 Khlong Sam Wa) is explained once on the Khlong Sam Wa year overview and on the Sources, method and limits page.

Lat Krabang, Ban Khlong Prawet and Nong Chok lie in the same rainfall cell, so their rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
