California State Climatologist
The California State Climate Office collects and interprets climate data for California, and disseminates climate data and information through various means including their website. The California State Climate Office is housed in the California Department of Water Resources' Division of Flood Management.
Regional Climate Data for each hydrologic region in California is provided on the website, with tables of regional climate normals based on the 1971-2000 period as well as climate normals for selected sites in a chosen region. 'The Weather and Climate Newsletter', written periodically by the State's weather and climate staff, is available through the California Data Exchange Center.
State Climate Offices are an integral component of the National Climate Service Partnership, which also includes NOAA's National Climatic Data Center and six Regional Climate Centers (RCCs). State climate offices recognized by the American Association of State Climatologists (AASC) work closely with one another, and with the regional and national counterparts, to provide climate data and services at the local level. Specifically, AASC recognized state climate offices (or ARSCOs) provide one or more of the following services:
1) Coordinate and collect weather observations for the purpose of climate monitoring; 2) Summarize and disseminate weather and climate information to the user community; 3) Demonstrate to the user community the value of climate information in the decision making process; 4) Perform climate impact assessments and weather event evaluations; 5) Conduct climate research, diagnosis, and projections.
The California State Climate Office is recognized by the AASC.
