Twelve-month representative atmospheric patterns measured from 1991 to 2020 at 4.4 meters elevation.
Review the long-term annual climate rhythm of Ketelmeer & Vossemeer through normalized monthly data. This record details mean temperatures, daily precipitation rates, relative humidity, wind speeds, and daylight hours for a singular representative coordinate within the protected area. These statistics provide a consistent baseline for analyzing the atmospheric environment, distinct from real-time weather forecasts or current meteorological events.
