Temperature and Dew Point
There are 5 weather stations near enough to contribute to our estimation of the temperature and dew point in Runnemede.
For each station, the records are corrected for the elevation difference between that station and Runnemede 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 Runnemede is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Runnemede and a given station.
The stations contributing to this reconstruction are: Philadelphia International Airport (47%, 14 kilometers, west); South Jersey Regional Airport (24%, 22 kilometers, northeast); North Philadelphia Airport (18%, 26 kilometers, north); Millville Municipal Airport (6%, 54 kilometers, south); and Atlantic City International Airport (4.9%, 62 kilometers, southeast).
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.
