Detour signThe Arizona Meteorological Network
(University of Arizona) has been in operation since 1986 providing meteorological data and weather-based information to agricultural and horticultural interests of the state. Meteorological data is collected from a network of automated weather stations located in both rural and urban production settings. Meteorological data collected by AZMET include temperature (air and soil), humidity, solar radiation, wind (speed and direction), and precipitation. AZMET also provides a variety of computed variables, including heat units (degree-days), chill hours, and reference crop evapotranspiration (ETo).
