Earth Science Data for All: EOS and the EOS Data and Information System

Earth Observing System (EOS) program addresses significant science questions, the answers to which bear di- rectly on vitally important environmental policy issues. The goals of EOS are to obtain a scientific understanding of the Earth as a system and to develop the capability to predict en- vironmental changes that may result from human activities. The entire suite of EOS-related endeavors - a comprehensive space-based observing system, a data and information sys- tem, and a multidisciplinary and interdisciplinary scientific research program that uses the data and information to im- prove our understanding of humankind’s impact on climate and the Earth’s environment - is a science and technology program in support of policy and resources decision-making. The observing portion of the program will acquire high- priority new measurements to combine with critical histori- cal and contemporary data sets. The
