Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

Rainfall Return Levels

49 years, 1961 to 2010

A day with at least 84.7 mm (3.3 in) of rain is expected about once in 2 years. A day with at least 232.6 mm (9.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Las Adjuntas: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	84.7 mm (3.3 in)
5 years	116.2 mm (4.6 in)
10 years	140.0 mm (5.5 in)
25 years	173.8 mm (6.8 in)
50 years	201.9 mm (7.9 in)	Longer than the 49 years of record
100 years	232.6 mm (9.2 in)	Longer than the 49 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 49 years of values from 1961 to 2010.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 237.5 mm (9.4 in) in 1976; 182.4 mm (7.2 in) in 1990; 146.1 mm (5.8 in) in 2008.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Las Adjuntas, at 1974 and 2004. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1974 ran 0.4 C (0.6 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2004 ran 0.7 C (1.2 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Las Adjuntas, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1974	+0.4	+0.6	likely	5
2004	-0.6	-1.2	likely	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
