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 7 Developing A Validated Regional Climate Model Global (left) and southwest US (middle) surface air temperature for Jan 1999 from the National Center for Atmospheric Research 20th century climate simulation contribution to the IPCC’s 4th Assessment.
