What is CIMIS in the context of California irrigation?

• A. California Information Management and Information Systems
• B. California Irrigation Management Information System
• C. California Integrated Management of Irrigation Systems
• D. California Immediate Management of Irrigation Supply

Answer: (B)

California Irrigation Management Information System (CIMIS) is a crucial program designed to assist in the efficient use of water for irrigation. It provides real-time weather data and information that helps landscape professionals and farmers make informed irrigation decisions based on environmental conditions. The system helps optimize water use, ensuring that plants receive the right amount of water without waste.

CIMIS stations, which are strategically located throughout California, collect weather-related data such as temperature, humidity, and rainfall. This information is vital for calculating evapotranspiration rates, which reflect the amount of water that needs to be replaced through irrigation. By utilizing CIMIS, irrigators can improve water efficiency and promote sustainable landscape practices.

The other options do not accurately represent this system or its purpose. For instance, terms like "Information Management and Information Systems," "Integrated Management of Irrigation Systems," or "Immediate Management of Irrigation Supply" do not capture the primary focus of CIMIS, which is centered specifically on irrigation management through comprehensive data collection and dissemination.
