A twelve-month profile of temperature, precipitation, and wind patterns at a representative coordinate.
The climate profile for Little Missouri National Grassland provides comprehensive long-term averages for temperature, precipitation, relative humidity, wind speed, and daylight duration. Derived from NASA POWER measurements between 1991 and 2020, this data offers a granular view of the atmospheric rhythm at a single representative elevation. These records serve as an essential foundation for understanding the annual meteorological cycles within this protected landscape in North Dakota.
