Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Fossil.
For each station, the records are corrected for the elevation difference between that station and Fossil 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 Fossil is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Fossil and a given station.
The stations contributing to this reconstruction are: The Dalles Municipal Airport (22%, 102 kilometers, northwest); Roberts Field-Redmond Municipal Airport (30%, 110 kilometers, southwest); Hermiston Municipal Airport (21%, 119 kilometers, northeast); and John Day State Airport (27%, 119 kilometers, southeast).
