Temperature and Dew Point
There is only a single weather station, Ixtepec Ox, in our network suitable to be used as a proxy for the historical temperature and dew point records of Acayucan.
At a distance of 168 kilometers from Acayucan, 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 Acayucan to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 27%, making the weight assigned to the weather station 73%.
