Temperature and Dew Point
There are 6 weather stations near enough to contribute to our estimation of the temperature and dew point in Arinsal.
For each station, the records are corrected for the elevation difference between that station and Arinsal 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 Arinsal is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Arinsal and a given station.
The stations contributing to this reconstruction are: Saint-Girons - Antichan (25%, 58 kilometers, northwest); Carcassonne-Salvaza (17%, 98 kilometers, northeast); Perpignan–Rivesaltes Airport (16%, 115 kilometers, east); Aeroport de Girona - Costa Brava (16%, 129 kilometers, southeast); Barcelona–El Prat Airport (13%, 150 kilometers, south); and Reus Airport (13%, 161 kilometers, south).
