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
6
JIFRESSE Strategy
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 data
3. 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.
2.
3.
4.
Coupled Model Development - Remote Sensing Data Analysis
Ecosystem Sensitivity Studies and Applications
Air Quality and Climate Sensitivity Studies and Applications
Sensor and Sensor Web Development
