In 1982, researchers from UC Cooperative Extension, UC Davis, and the California Department of Water Resources teamed up to develop a system to help growers and landscapers water more efficiently. Together they created the California Irrigation Management Information System (CIMIS), a network of 120 automated weather stations across California that calculate the local rate of water loss to the atmosphere through evaporation and plant transpiration. With this real-time and archived information, growers and landscapers are able to make better-informed decisions about when and how much to irrigate. A 2000 report from UC Berkeley put CIMIS-related increases to state agricultural profits at about $64,666,000 per year. CIMIS has dramatically improved irrigation in the Golden State, and not just for agriculture. CIMIS users include school districts, fire departments, utility companies, government organizations, and more.
