Temperature and Dew Point
There is only a single weather station, General Juan N. Álvarez International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of San Juan Ihualtepec.
At a distance of 190 kilometers from San Juan Ihualtepec, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere .
The weight assigned to the MERRA-2 value depends on the distance from San Juan Ihualtepec to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 45%, making the weight assigned to the weather station 55%.
