Long term climatological data covering temperature, moisture, and daylight cycles
Analysis of the climate at a representative coordinate within Cedar River National Grassland using NASA POWER data from 1991 to 2020. Measurements trace the annual rhythm of average minimum and maximum temperatures, daily precipitation rates, relative humidity, wind speeds, and seasonal daylight shifts. Data points reflect long term averages rather than current weather patterns or specific site conditions across the grassland area.
