The temperature of the air as observed at 1.2 meters above the ground surface. There are five factors that determine this: latitude, surface type, coastal or interior location, elevation and atmospheric and oceanic circulations.
Mean Daily Temperature
The average of the maximum and minimum daily values.
Mean Monthly Temperature
The average of mean daily temperatures in a month.
Urban Heat Islands
A location with a significantly elevated temperature due to the effects of an urbanized area.
The decrease in air temperature with increasing altitude.
Environmental Temperature Lapse Rate
The average value demonstrating how many degrees are dropped as elevation increases (3.56 degrees Fahrenheit per 1000 feet).
