The UCLA/JPL Joint Institute for Earth System Science and Engineering (JIFRESSE) is a new partnership model (created May, 2006) Located at UCLA (includes
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

The overall plan seeks to
1. Develop modeling tools for understanding regional scale response to climate change
2. Validate the modeling tools with available observational data3. 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 Applications3. Air Quality and Climate Sensitivity Studies and Applications4. Sensor and Sensor Web Development
