Detailed atmospheric records including wind speed, relative humidity, and daylight hours for the landscape
Annual climate rhythms for Parc naturel Viroin-Hermeton are defined through representative-point measurements of average temperatures, daily precipitation rates, and atmospheric humidity levels. Data profiles track consistent monthly averages for wind speed and daylight duration based on records from 1991 to 2020. These metrics provide a grounded view of the long-term climatic environment, distinct from daily weather fluctuations or site-wide variability across the protected area.
