The new service will provide reporters with timely responses to their questions about the science of climate change.

Crop yields are affected by many factors, including breeding, management, and climate. New research from NCAR seeks to better understand these factors and their contributions to historical yield increases, in order to anticipate future changes.

International collaboration has always been at the heart of COSMIC, a six-satellite network that intercepts GPS signals to measure weather, climate, and space weather variables. Now one of the leading university collaborators on COSMIC, the University of Graz, is UCAR’s latest international affiliate.
