Observations from space over the past 50 years have fundamentally transformed the way people view the Earth. The National Research Council report Earth Observations from Space: The First 50 Years of Scientific Achievements (2008) describes how satellites have revolutionized Earth studies and ushered in a new era of multidisciplinary Earth sciences. Satellite observation has also given us a valuable source of information about ocean color, vital to understanding the health of the ocean ecosystem, as described in the National Research Council report Assessing Requirements for Sustained Ocean Color Research and Operations (2011).
Over the past 50 years, thousands of satellites have been sent into space on missions to collect data about the Earth. Today, the ability to forecast weather, climate, and natural hazards depends critically on these satellite-based observations. At the request of the National Aeronautics and Space Administration, the National Academies published the report Earth Observations …View full post
Report: Assessing Requirements for Sustained Ocean Color Research and Operations Satellite measurements of ocean color provide a unique global perspective on the health of the ocean by allowing scientists to track changes in the abundance and productivity of phytoplankton, microscopic organisms that live in the ocean’s surface waters and form the base of the marine food …View full post
Satellite information can now be gathered frequently enough to provide, as in a movie, a view of the complex and dynamic nature of the Earth system. These animations, which show actual satellite data and are not cartoons or drawings, show how space observations now enable quantitative measurements of properties such as temperature, concentrations of atmospheric …View full post
