The Gateway to Astronaut Photography of Earth
No full textThis Web site hosts the most complete online collection of astronaut photographs of the Earth, including over 600,000 photos from Space Shuttle and the International Space Station. Users can search the database of photos by geographic coordinates or region, mission, features, cloud cover and many other options. The site also features an image of the week, as well as special collections of images, including: Cities, Earth Landscape, Earth-Human Interaction, Distinctive Features, Hurricanes and Weather, Earth's Water Habitat and Geographical Regions. Educational levels: Middle school, High school, Undergraduate lower division, Informal education, General public
Spacecraft Reaction Wheels
Get PDFThis activity is designed to introduce the engineering aspects of precision pointing of spacecraft. Educational levels: Middle school, High school, Middle school, High school
Space Math: Radiation Math
Get PDFThis booklet includes 19 problems that explore the topic of radiation and human exposure to its different forms. The problems span math abilities from basic multiplication and unit conversions, to algebra and calculus. For example, students learn about the various natural radiation dosages to which they are exposed daily, work quantitatively with authentic radiation dosage units to estimate the total annual dosages resulting from different lifestyles, and determine probabilities of occurrence for flares and other radiation events in space. Math skills include graph analysis, Venn diagramming, probability and statistics, evaluating equations in more than one variable, extrapolation and forecasting, scientific notation, integral calculus. (8.5 x11, 28 pages, 11 color images, PDF file) Educational levels: Intermediate elementary, Middle school, High school
Is Greenland Melting?
No full textIn this chapter, using My World GIS, users explore data that characterize the dynamic Greenland Ice Sheet. By examining photographs, map views, and tabular data, users gain an understanding of how and why scientists are monitoring the ice sheet and what they are finding. Users explore map layers that represent ice sheet thickness, weather station locations, and annual melt extents of the ice sheet. They learn about the working conditions that Arctic scientists must endure to collect their data, and how sensors on satellites are used to gather information from an area as large as Greenland. Finally, users learn about scientists' methods for measuring ice flowing downhill from Greenland, and examine that data to learn how fast the ice is moving.

SKYWARN® Spotter Training
No full textThis course covers the basics of being a SKYWARN Spotter. The goal of the course is to provide baseline training for all spotters through multiple modules covering the procedures for spotting (including communication and spotter report criteria) and safety considerations for all hazards. You can choose to register as a SKYWARN Spotter with the National Weather Service (NWS) by using the checkbox that appears after you Enroll in the course. If you check the box, you may be able to register with the NWS after passing the course. Your local NWS Warning Coordination Meteorologist will determine if there is additional training on other weather hazards, such as heavy snow, ice storms, floods, etc., and their reporting that must be completed through local spotter training. Educational levels: Graduate or professional
Distributed Hydrologic Models for Flow Forecasts - Part 2
No full textDistributed Hydrologic Models for Flow Forecasts Part 2 is the second release in a two-part series focused on the science of distributed models and their applicability to different flow forecasting situations. Presented by Dr. Dennis Johnson, the module provides a more detailed look at the processes and mechanisms involved in distributed hydrologic models. It examines the rainfall/runoff component, snowmelt, overland flow routing, and channel response in a basin as represented in a distributed model. Calibration issues and situations in which distributed hydrologic models might be most appropriate are also addressed. Educational levels: Graduate or professional
Tsunami Warning Systems
No full textTsunami Warning Systems describes the processes involved in anticipating, detecting, and warning for a tsunami by summarizing data collection, modeling, analysis, and alert procedures used at NOAA's Tsunami Warning Centers. A simulated event and past tsunami occurrences are used to highlight warning system processes for determining the tsunami threat based on seismic and sea level data and tsunami forecast models. Message communication and local response are also addressed as final components of any warning system. The module is intended for Weather Forecast Office staff and emergency managers who require a better understanding of the technical aspects of tsunami warning delivery. The module will also benefit anyone wanting to learn more about the components of tsunami warning systems. Educational levels: Graduate or professional
Event-Based Science: Remote-Sensing Activities
No full textThese activities enable students to use remotely-sensed data- as they tackle the real-world problems and tasks found in existing Event-Based Science (EBS) modules. Remotely-sensed data are employed as an integral part of both the presentation of Earth system science concepts, and in the solutions to real-world problems. The activities emphasize the use of NASA remote-sensing data from satellites and sensors including: Landsat, GOES, and MODIS, and SeaWiFS. The EBS remote-sensing activities enhance EBS modules, including: Blight! Earthquake! Fire! Flood! Hurricane! Oil Spill! and Volcano! Educational levels: Middle school
Accessing and Downloading Images from NASA's WISE Mission
No full textThis website provides instructions on how to find and download images directly from the WISE archive. Anyone with an internet connection now has free access to high-resolution infrared images from the WISE mission. These instructions explain how to get the images you want, without using complex terminology and options that may be difficult for the layperson to navigate. Educational levels: Informal education, General public
Exploring the Environment
No full textThese on-line, problem-based modules address events such as volcanoes, hurricanes, dinosaur extinction theories, deforestation, endangered species, and global climate change. The site uses NASA remote-sensing images and includes a tutorial about how to analyze Landsat images with NIH Image. Educational levels: Middle school, High school
