Heat Units
Environmental temperatures impact the development of biological organisms that do not regulate their internal temperature, including crops and crop pests. Heat unit systems quantify the thermal environment of these organisms and are commonly used in phenology models - models that relate organism growth and development to local weather/climate conditions. This bulletin provides an overview of the heat unit concept and the two methods commonly used to compute heat units, then provides examples of how heat units can assist with the management of agricultural production systems in Arizona and concludes with a discussion on how to obtain local heat unit information.
