Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Ames Lake.
For each station, the records are corrected for the elevation difference between that station and Ames Lake 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 Ames Lake is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Ames Lake and a given station.
The stations contributing to this reconstruction are: Renton Municipal Airport (61%, 24 kilometers, southwest); Snohomish County Airport (Paine Field) (33%, 39 kilometers, northwest); and Stampede Pass (6%, 62 kilometers, southeast).
