NEO is NASA's Earth Observation web-based tool designed to help students picture, explore, analyze, and understand patterns of environmental change using satellite images. NEO combines a user-friendly but powerful set of exploratory and analytical tools with a wide range of NASA's remotely sensed (satellite) data, allowing students and teachers to investigate Earth system components of atmosphere, oceans, land, life, and energy.
In this exercise, students will learn how to select, explore, and analyze satellite imagery, all in the context of a case study of the Earth's energy budget. They will learn how to display, graph, analyze, and evaluate variation, and more powerfully, covariation, in Outgoing Longcase Radiation (heat from the Earth's surface) and cloud cover anywhere on Earth. In this way, students can see how outgoing radiation and cloud cover vary from place to place and from month to month. By exploring and understanding variation and covariation, they will be able to these two important and highly dynamic Earth - Atmosphere components interact across the globe.
