Does the institution use weather data or weather sensors to automatically adjust irrigation practices?:

A brief description of how weather data or sensors are used:

The campus uses a Rainmaster ll weather station, which uses sensors to record data and produces an evapotranspiration factor daily. Irrigation run times are adjusted automatically by the central irrigation computer. There is also a rain gauge that will shut off the system when a certain threshold of precipitation is reached in a specified time. It is a state-of-the-industry system, used on the Davis campus. The campus is one of the largest operators of this system on the West Coast, and the irrigation staff are trained professionals who are members in an irrigation association that encourages education and certification for irrigation professionals.
