5. UCLA Earth Science Focuses on Modeling and Data Analysis Hurricane Katrina Ice/snow mixing ratio fields at 300 mb (4 km WRF simulation, R. Fovell, 2007) • Departmental Focus • GCM and Climate Modeling • Aerosols and Clouds in Climate • Mesoscale Modeling and Prediction • Air-Sea Interactions • Coastal Oceanography • Air Pollution & Atmospheric Chemistry • Remote Sensing & Radiation • Land-Atmosphere Interactions • Biogeochemical Cycle

6. Addressing California Climate Challenges through Research Partnerships • The UCLA/JPL Joint Institute for Earth System Science and Engineering (JIFRESSE) is a new partnership model (created May, 2006) • Located at UCLA (includes Director, Chief Operating Officer, 2 Adjunct Professors) • Promotes exchanges between faculty, students and researchers • Joint funding • Focuses on understanding regional impacts of climate change, through both modeling and observations • Contributes to robust predictions of California’s future environmental conditions, including air quality, snowpack and fresh water

7. JIFRESSE Strategy • The overall plan seeks to • Develop modeling tools for understanding regional scale response to climate change • Validate the modeling tools with available observational data • Develop techniques for observations of climate and environmental processes at the required spatial and temporal resolutions. • The initial plan for the joint institute is to focus on four Earth System Science and Engineering thrust areas, namely: • 1. Coupled Model Development - Remote Sensing Data Analysis • 2. Ecosystem Sensitivity Studies and Applications • 3. Air Quality and Climate Sensitivity Studies and Applications • 4. Sensor and Sensor Web Development
