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 Tempe campus specifies Calsense controllers for all new installations and renovations. The Polytechnic campus also uses the water management system called Calsense. This system calculates water requirements from an initially established baseline which is programmed for desert adapted plants. It measures rain fall and adjusts metering as needed in addition to accounting for time of day and the evapotranspiration rates for the landscaped vegetation. The current system monitors a substantial portion of the campus core. Coverage equals approximately 1,007,376 square feet which is a substantial portion of our campus. The majority is left wild and plans for switching the rest of the scaped areas include reliance on weather gages to ensure optimal water use. The Tempe campus specifies Calsense controllers for all new installations and renovations.
