Temperature and Dew Point
There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Tlacuilolapan.
For each station, the records are corrected for the elevation difference between that station and Tlacuilolapan 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 Tlacuilolapan is computed as the weighted average of the individual contributions from each station, in addition to a contribution from the MERRA-2 reconstruction, corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Tlacuilolapan.
The station weigths are proportional to the inverse of the distance between Tlacuilolapan and a given station.
The weight assigned to the MERRA-2 value depends on the distance from Tlacuilolapan to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 25%.
