This classroom activity explains how clouds and pollution in the atmosphere are important to climate, and the need to study whether pollution may be changing Earth's climate in undesirable ways. It introduces NASA's Multi-angle Imaging SpectroRadiometer (MISR) mission. The activity includes building a MISR-lite model to demonstrate how looking at the same thing (i.e., Earth's atmosphere) from different ... Full description.

This classroom activity explains how the Global Positioning System (GPS) satellites work to provide precise location information to positions on the ground, as well as to other satellites whose job is to map the surface of Earth. The activity is specifically tied to NASA's Jason-1 and Topex/Poseidon spacecraft in their mission to map ocean topography. In addition to the concepts of distance vs. time ... Full description.

The National Weather Service provides weather and marine data from buoys surrounding North America, the Carribean, and Great Britain. Historical and realtime data are featured. Data include wind, waves, atmospheric pressure, air and water temperature, and dewpoint. Frequently Asked Questions explain how the marine stations collect and transmit data, how quality is assured, and how the National Data ... Full description.

This lesson is designed to help students gain knowledge in accessing current weather data and in using the MY NASA DATA Live Access Server (LAS) to specify and download historical satellite data. Students then use the data to examine the relationship between altitude, atmospheric pressure, temperature and humidity at a particular location. In this lesson, weather data from ground-based and satellite ... Full description.

In this lesson, students will examine authentic NASA satellite data to explore how hurricanes extract heat energy from the ocean surface. They will practice finding data via the Internet and make line plots and data maps. Students will understand how hurricanes gain energy from the ocean surface. They will form a hypothesis, compare data parameters and draw conclusions. Full description.

This book explains the Earth system using three concepts: 1.The cycles of matter; 2.The flows of energy; and 3.The web of life. It then applies these concepts to real-life problems and issues that affect us and our planet. Full description.

The purpose of NASA's Earth Observatory is to provide a freely accessible publication on the Internet where the public can obtain new satellite imagery and scientific information about our home planet. The focus is on Earth's climate and environmental change. The site is divided into six main sections: Data and Images, Features, News, Reference, Missions, and Experiments. The Data and Images, Features, ... Full description.
