Annual patterns in temperature, precipitation, and atmospheric variables for the reserve
Detailed monthly climate profiles for Mono Transboundary Biosphere Reserve demonstrate long-term patterns based on NASA POWER measurements from 1991 to 2020. This data includes average maximum, mean, and minimum temperatures, alongside daily precipitation rates, relative humidity, wind speed, and daylight hours. These values represent a single fixed coordinate within the reserve, providing a standardized look at regional atmospheric behavior across the full calendar year.
