Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Sparta.
For each station, the records are corrected for the elevation difference between that station and Sparta 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 Sparta is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Sparta and a given station.
The stations contributing to this reconstruction are: Crossville Memorial Airport (57%, 35 kilometers, east); Smyrna Airport (18%, 96 kilometers, west); Lovell Field (16%, 102 kilometers, south); and Huntsville Airport North (9%, 155 kilometers, southwest).
