Review temperature, precipitation, wind, and daylight norms derived from 1991 to 2020 climatology data.
Analyze the long term climate rhythm at a representative coordinate within Naturschutzgebiet Oberes Ruhrtal through standardized monthly averages. These metrics provide a consistent reference for temperature fluctuations, daily precipitation rates, relative humidity, wind velocity, and daylight duration from 1991 to 2020. This data clarifies the atmospheric patterns of this nature reserve in North Rhine-Westphalia without reflecting short term weather volatility.
