Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Hamilton.
For each station, the records are corrected for the elevation difference between that station and Hamilton according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Hamilton is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Hamilton and a given station.
The stations contributing to this reconstruction are: Missoula International Airport (43%, 75 kilometers, north); Lowell (20%, 111 kilometers, west); Lemhi County Airport (20%, 128 kilometers, south); and Bert Mooney Airport (17%, 132 kilometers, east).
