By definition, observations expose processes and impacts that have already occurred, or are ongoing. But they also underpin our ability to predict future change. For example, observations are used to test and evaluate models that predict long-term global change, and to inform short-term weather forecasts.
As demand for deeper understanding of the complex and changing Earth system continues to grow, America will be faced with increasing pressure to maintain and improve upon existing capabilities, as well as to develop new, better integrated observing systems. Building such observational capacity is essential to advancing scientific progress, enhancing national
