CIMIS, co-established by UCCE, melds current weather data with specific crop water needs

Sediment monitoring
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.
