The fitted trend in annual mean temperature here over 1905 to 1955 is 0.1 C (-0.1 to 0.3) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.2 F (-0.2 to 0.5) per decade. The slope is a straight line fitted to 44 complete years; the brackets give its 95 percent interval.

A year is complete when all 12 months have at least 20 days of both daily maximum and daily minimum readings. The annual mean is the mean of the monthly means. The trend describes this one station over this period; it does not say what caused the change.

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.

Frost Dates and Growing Season

44 years with a frost

Across 44 years with a frost, the median last spring frost at Glacier falls on 4 June and the median first autumn frost on 10 September, which leaves a median of 94 days between them.

Fitted over all years, the growing season changes by -4.1 days per decade at this station.

Frost dates and growing season at Glacier

First autumn frost10 Septembern/a8 Septembern/a-4.4 days per decade
Growing days94 daysn/a93 daysn/a-4.1 days per decade

A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.

Rainfall Return Levels

48 years, 1894 to 1955

A day with at least 42.5 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 95.7 mm (3.8 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 48 years of values from 1894 to 1955.

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: 82.6 mm (3.3 in) in 1918; 78.7 mm (3.1 in) in 1909; 74.9 mm (2.9 in) in 1939.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Glacier, at 1926 and 1948. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1926 ran 0.6 C (1.1 F) lower than in the years before (possible change).
  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1948 ran 0.6 C (1.0 F) higher than in the years before (possible change).

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.
