Temperature and Dew Point
There are 5 weather stations near enough to contribute to our estimation of the temperature and dew point in Gold Bar.
For each station, the records are corrected for the elevation difference between that station and Gold Bar 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 Gold Bar is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Gold Bar and a given station.
The stations contributing to this reconstruction are: Snohomish County Airport (Paine Field) (35%, 44 kilometers, west); Arlington Municipal Airport (30%, 48 kilometers, northwest); Renton Municipal Airport (23%, 56 kilometers, southwest); Stampede Pass (7%, 70 kilometers, southeast); and Omak Airport (4.4%, 175 kilometers, northeast).
