For each station, the records are corrected for the elevation difference between that station and Chico 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 Chico is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Chico and a given station.
The stations contributing to this reconstruction are: Chico Municipal Airport (87%, 8 kilometers, north); Oroville Municipal Airport (11%, 33 kilometers, southeast); and Ukiah Municipal Airport (1.3%, 135 kilometers, southwest).
