Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Dewey-Humboldt.
For each station, the records are corrected for the elevation difference between that station and Dewey-Humboldt 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 Dewey-Humboldt is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Dewey-Humboldt and a given station.
The stations contributing to this reconstruction are: Ernest A. Love Field (68%, 21 kilometers, northwest); Sedona Airport (19%, 55 kilometers, northeast); Payson Airport (9%, 88 kilometers, east); and Phoenix-Deer Valley Airport (4.7%, 95 kilometers, south).
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
