Temperature and Dew Point
There are 5 weather stations near enough to contribute to our estimation of the temperature and dew point in Cambridge.
For each station, the records are corrected for the elevation difference between that station and Cambridge 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 Cambridge is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Cambridge and a given station.
The stations contributing to this reconstruction are: McCook Ben Nelson Regional Airport (44%, 37 kilometers, west); Jim Kelly Field (19%, 66 kilometers, northeast); Brewster Field (17%, 73 kilometers, east); North Platte Regional Airport Lee Bird Field (10%, 103 kilometers, northwest); and Hill City Municipal Airport (10%, 105 kilometers, south).
