Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Old River-Winfree.
For each station, the records are corrected for the elevation difference between that station and Old River-Winfree 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 Old River-Winfree is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Old River-Winfree and a given station.
The stations contributing to this reconstruction are: Ellington Field (44%, 43 kilometers, southwest); George Bush Intercontinental Airport (32%, 52 kilometers, west); and Beaumont Municipal Airport (24%, 64 kilometers, east).
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.
