Twelve month statistical profile of temperature, precipitation, and light patterns
Annual climatology data for St. Denis National Wildlife Area, derived from NASA POWER measurements between 1991 and 2020 at a single representative coordinate. These records define long term trends in minimum and maximum temperatures, daily precipitation, relative humidity, wind speed, and daylight hours. This data provides a consistent reference for the local atmospheric patterns experienced across the calendar year.
