Scientific progress and discovery increasingly hinge upon analysis of a wide variety of data sources. With these datasets growing ever larger and more complex, we are increasingly challenged in the areas of management, preservation, integration, and access to high-level services that facilitate inquiry and hypothesis testing. We are also seeing an increase in geographically distributed resources. For science to advance, we must develop new knowledge-based environments that allow researchers to easily query and analyze vast holdings of diverse, distributed data. NCAR has joined a number of collaborations aimed at addressing critical science and societal challenges, ranging from the Intergovernmental Panel on Climate Change (IPCC), the International Polar Year, regional climate modeling, solar-terrestrial science, digital preservation, and more. We will survey these areas, discuss some of the challenges we face in developing effective cyberinfrastructure, and briefly touch on the important migration towards "science gateways" and knowledge-based environments.
