What is CalClim?www.calclim.dri.edu

Monitor climate variabilityand change in CaliforniaProvide a reliable sourcefor climate data andinformation via CaliforniaClimate Data Archive(CCDA)California Climate Watchonline newsletterTarget audience:researchers, govtagencies, publicinterested in CA climate

www.calclim.dri.edu

www.calclim.dri.edu

Why do we need CCDA?Current California climate datasourcesNWS Cooperative (COOP) network:

daily temp & precipSnowpack Telemetry (SNOTEL): snow depth and water contentRemote Automated Weather Stations (RAWS):

hourly temps (air, fuel, RH, dew point), wind, precip, solar radiationSurface Airways (SAO/METAR):

hourly observations, mainly airportsCalifornia Data Exchange Center (CDEC):

includes state Snow Survey sites, time periods varyCalifornia Irrigation Management Information System (CIMIS):

Central valley, agriculture-focused network including temps, precip, wind, solar radiation & calculated ET

NOAA buoys & many small coastal area networksCalifornia Air Resources Board (CARB), air quality, some met.

Current CalClim Activities:Coastal Climate Data Archive

Data sets include:NOAA buoys, CMANstations, lighthouses, otheroffshore observingnetworks and “special”sites such as Scripps PierAlso cooperating withCeNCOOS and otherregional IOOS (IntegratedOcean Observing System)

www.calclim.dri.edu

Current CalClim Activities:Air Quality Data

How can these data fit in to a traditionallymeteorological database?Are we monitoring climate change, or monitoringthe factors that cause/influence the climate?California is leading the way in air quality andclimate monitoring.

SummaryWe have a variety of research activities in CaliforniaWRCC offers a host of data and products onlineBut, CalClim and the CCDA are providing“enhanced” climate information for FREEWe strive for detailed, long-term climate data andinformation for monitoring and research studies

Now you know what we do…We’re always open to ideas for research &suggestions on how to improve our services
