Twelve-month climate cycles for temperature, precipitation, and daylight patterns
Detailed analysis of atmospheric variables for Réserve naturelle régionale de la Massonne based on NASA POWER records from 1991 to 2020. Average temperature, precipitation rates, relative humidity, wind speed, and daylight duration provide a consistent look at the regional climate. Each monthly value reflects measurements from a single representative point at 5.23 meters of elevation.
