Twelve-month statistical analysis of temperature, precipitation, wind, and daylight duration
Detailed atmospheric records for Joseph Battell Wilderness based on NASA POWER climatology from 1991 to 2020. This data provides a representative point profile at 281 meters, detailing monthly shifts in mean, minimum, and maximum temperatures alongside precipitation rates, relative humidity, and wind speed. These long-term averages support geographic understanding of annual meteorological rhythms within this protected area, distinct from seasonal weather forecasts.
