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 Mercier–Hochelaga-Maisonneuve) is explained once on the Mercier–Hochelaga-Maisonneuve year overview and on the Sources, method and limits page.

Montréal, Longueuil and Villeray–Saint-Michel–Parc-Extension lie in the same rainfall cell, so their rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
