Tracking annual patterns in temperature, precipitation, wind, and daylight duration
Examine the twelve-month climate profile for Rouge National Urban Park based on NASA POWER measurements collected between 1991 and 2020. This data provides long-term averages for mean temperature, daily precipitation rates, relative humidity, wind speed, and daylight hours at a single representative coordinate. These statistics serve as a consistent reference for understanding the atmospheric character of the park throughout the calendar year.
