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 Barra da Tijuca) is explained once on the Barra da Tijuca year overview and on the Sources, method and limits page.

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