The objective of this project is to develop and test a set of indicators of extreme events under a changing climate that have relevance for preparedness and adaptation within the air and water quality sectors in California. We will do this by integrating information from historical climate data, downscaled climate model simulations of current and future climate, and air and water quality managers' understanding of the vulnerabilities of their systems. The research is motivated by the expressed desire of resource managers to have more relevant and accessible climate change information to improve management of climate risks. By working with resource managers and climate scientists, we will develop more relevant definitions of extreme events to guide the development of policy-relevant climate impacts data.


The project will employ a bottom-up/top-down methodology that integrates inputs from resource managers and climate scientists. Surveys and interviews will be used to gather information from resource managers on past and future risks of extreme events and to identify the type of information they need to manage those risks. Case studies will integrate this information with analysis of past climate data and downscaled climate model simulations from the state-of-the-art set of experiments being developed as input to the next IPCC assessment cycle.

Expected Results:

Together, these methods will be used to develop a policy-relevant, interpretable and accessible set of indicators of extreme event risks for air and water quality management under a changing climate. These indicators will demonstrate how the most up-to-date climate projection data and historical information can be used to inform management of the risks of extreme events. Development of these indicators will serve as an educational exercise for both resource managers and climate scientists. Resource managers will learn about the potential for current climate science to address their information needs and where uncertainties and limitations remain, and the climate science community will learn about impact-relevant measures of extremes towards which further analysis efforts may be directed in the future.
