This report illustrates the typical weather in Shannon year round, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Shannon.
For each station, the records are corrected for the elevation difference between that station and Shannon 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 Shannon is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Shannon and a given station.
The stations contributing to this reconstruction are: Richard B Russell Airport (82%, 8 kilometers, west); Cartersville Airport (12%, 31 kilometers, southeast); and Dalton Municipal Airport (6%, 47 kilometers, northeast).
