John Callahan, associate scientist for the Delaware Geological Survey, has been selected to serve on a panel for the U.S. Climate Variability and Predictability (CLIVAR) Program. The program is jointly sponsored by NASA, NOAA, NSF and DOE. Callahan will serve on the Predictability, Predictions and Applications Interface (PPAI) Panel, which plays a critical role in the development of plans to foster the understanding of predictability of the oceans and climate across timescales, as well as improved practices in the provision, validation and use of climate information and forecasts through coordinated participation within the U.S. and international climate science and applications communities. The U.S. CLIVAR Panels are actively engaged in implementing activities to address the goals and strategies outlined in the U.S. CLIVAR Science Plan.
