Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Hollis.
For each station, the records are corrected for the elevation difference between that station and Hollis 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 Hollis is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Hollis and a given station.
The stations contributing to this reconstruction are: Childress Municipal Airport (46%, 45 kilometers, southwest); Altus Municipal Airport (37%, 53 kilometers, east); Hemphill County Airport (8%, 142 kilometers, north); and Perry Lefors Field (8%, 143 kilometers, northwest).
