Temperature and Dew Point
There are 5 weather stations near enough to contribute to our estimation of the temperature and dew point in Rosedale.
For each station, the records are corrected for the elevation difference between that station and Rosedale 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 Rosedale is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Rosedale and a given station.
The stations contributing to this reconstruction are: Meadows Field (92%, 10 kilometers, northeast); Sandberg (1.7%, 81 kilometers, southeast); Santa Ynez Airport (2.4%, 121 kilometers, southwest); Santa Barbara Municipal Airport (2.3%, 124 kilometers, southwest); and Paso Robles Municipal Airport (2.0%, 138 kilometers, west).
