Applying climate data in resource management requires matching spatial scales of climate and resource databases. ClimateBC (Wang et al. 2006a) is a computer program that does this for historic monthly temperature and precipitation and climate change scenarios for BC. Applications of these data including predicting ecological changes, tree seed selection, hydrological impacts, and economic impacts of insects under climate change (e.g., Hamann and Wang 2006, Wang et al. 2006b, Spittlehouse 2006a,b, PCIC 2007). These studies and numerous enquiries by professionals from a range of disciplineshave identified the need to improve the products available and to provide easy access to gridded temperature and precipitation data fdor use in geographic information systems.

Gridded temperature and precipitation data will be generated for the 1961-1990 and 1971-2000 normals period and for monthly historical data of the last century. We will expand the range of for the 400 m gridded data and also produce data at 0.5 arcminute to mach te data currently available for the contiguous United States. We will also generated a selection of climate change scenarios from the Fourth Assessment (IPCC WG I 2007), with allowance for the new reference period for these data. The Pacific Climate Impacts Consortium (PCIC) will host the gridded data files and provide the on-line delivery system, equivalent to similar services for the United States ( The University of BC will continue to host the stand alone version of CimateBC and a web version. We will review the option of providing on-line access to other gridded data sets such as CANGRID (McKenny et al. 2001, McKenney et al. 2006) to provide users with a choice of databases. Mechanisms for accessing gridded data and on-line delivery to the user will be developed and implemented under this proposal.

There is interest in assessing effects of inter-annual variability on forest and range resources. We will assess what is required in creating and making available time series (present to 2099) of monthly temperature and precipitation data for selected climate change scenarios through the PCIC system.
