Seasonal Changes

Catalog #: 025-06-0007
Parent Exhibit: A View From Space
Description: At this station, visitors spin a praxinoscope and see an entire year of satellite data from North America compressed into a few seconds of animation. Complex patterns of change are revealed as visitors watch cycles of drought, snow accumulation, and vegetation growth across the continent. Images in this animation are taken from NASA’s “Blue Marble: Next Generation” data set. This set of images was created using data from the MODIS (Moderate-Resolution Imaging Spectroradiometer) sensor aboard the Terra satellite and features a year of monthly composite images of the entire globe. NASA scientists used computer programs to remove clouds and enhance details in the images. Key message: Changes on the surface of the Earth are visible from space. Student Challenge: Spin the wheel. What changes do you notice? Why do you think the color of the East coast changes so much during the year?
