Daily Summaries for Apgar

Elevation: 5174 feet

A meteorological station located at Apgar Mountain in Glacier National Park, MT, collected temperature, wind, solar radiation, and relative humidity data intermittently from 1994 to 1997. All data are preliminary and subject to change. Daily temperature summaries of these data are illustrated below. Each day is represented by a 24 hour average. Days with less than 24 hours of recorded data are represented as missing days.



Figure 1.0 Average daily temperatures at Apgar Mountain in Glacier National Park, MT, years 1994-1997. Each year (water year) runs from October 1 through September 30. The daily value is an average of 24 hourly average values. Any day with less than 24 hours of data is excluded from this data set and represented by missing data.





Figure 1.1 Maximum daily temperatures at Apgar Mountain in Glacier National Park, MT, years 1994-1997. Each year (water year) runs from October 1 through September 30. The daily Tmax value is the highest of 24 average hourly temperatures. Any day with less than 24 hours of data is excluded from this data set and represented by missing data.





Figure 1.2 Minimum daily temperatures at Apgar Mountain in Glacier National Park, MT, years 1994-1997. Each year (water year) runs from October 1 through September 30. The daily Tmin value is the lowest of 24 average hourly temperatures. Any day with less than 24 hours of data is excluded from this data set and represented by missing data.





Figure 2.0 Annual number of days when maximum daily temperature is greater than 60 degrees Fahrenheit at Apgar Mountain in Glacier National Park, MT, years 1994-1997. Each year (water year) runs from October 1 through September 30. Any day with less than 24 hours of data is excluded from this data set and represented by missing data. Missing days are represented by error bars.
