Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Granite.
For each station, the records are corrected for the elevation difference between that station and Granite 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 Granite is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Granite and a given station.
The stations contributing to this reconstruction are: Altus Municipal Airport (40%, 30 kilometers, south); Hobart Regional Airport (40%, 30 kilometers, east); and Clinton-Sherman Airport (20%, 47 kilometers, north).
