Twelve-month atmospheric overview based on representative coordinate data from 1991 to 2020
Annual climatic patterns at Südwest-Naturreservat are characterized through monthly averages for temperature, precipitation, relative humidity, wind speed, and daylight hours. These records rely on NASA POWER measurements collected between 1991 and 2020 at a specific representative coordinate. Consistent tracking of these baseline metrics assists in understanding the long-term atmospheric rhythm of the reserve independent of daily weather fluctuations.
