Twelve-month climatology profile using representative coordinates from the 1991 to 2020 period
Analyze the long-term atmospheric patterns within the Dyfi Biosphere through a structured monthly climate dataset. This profile details average minimum, mean, and maximum temperatures alongside daily precipitation rates, relative humidity, wind speeds, and daylight hours. All measurements represent stable long-term norms at a specific coordinate rather than current weather forecasts or site-wide conditions.
Analyzing long term monthly thermal ranges alongside average daily precipitation rates across the calendar year
Analyze long term monthly averages for temperature bounds, precipitation rates, wind speeds, humidity, and calculated daylight across the calendar year.
