Temperature and Dew Point
There are 5 weather stations near enough to contribute to our estimation of the temperature and dew point in Moro.
For each station, the records are corrected for the elevation difference between that station and Moro 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 Moro is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Moro and a given station.
The stations contributing to this reconstruction are: The Dalles Municipal Airport (45%, 37 kilometers, northwest); Hermiston Municipal Airport (16%, 121 kilometers, east); Yakima Air Terminal Airport (17%, 122 kilometers, north); Roberts Field-Redmond Municipal Airport (13%, 140 kilometers, south); and John Day State Airport (9%, 184 kilometers, southeast).
