Long term atmospheric records including relative humidity, wind speed, and daylight hours
Analysis of atmospheric conditions at Utrechtse Heuvelrug National Park using twelve month climate normals from the 1991 to 2020 period. Measurements at the representative coordinate include average minimum and maximum temperatures, daily precipitation rates, relative humidity, wind velocity, and daylight duration. These records provide a consistent baseline for understanding the annual meteorological rhythm of the park landscape without reference to current weather or daily forecasts.
