|Parent Exhibit: Eyes on Earth|
|Description: This two-sided banner shows ten images of the planet, each created using data from a different satellite sensor. Most satellite sensors collect data by measuring different wavelengths of light. For example, the MODIS sensor on the Terra satellite can measure long wave infrared radiation. This information allows scientists to create global temperature maps of the oceans and lands. The TOPEX/Poseidon satellite, in contrast, used radar to measure ocean surface heights. This data can also be used to calculate ocean temperatures. For the large “Blue Marble” image, cloud, land, and ocean data were collected by three different satellites: the Geostationary Operational Environmental Satellite (GOES), the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) satellite, and NOAA's Polar Orbiting Environmental Satellite (POES). In the image a powerful hurricane is visible in the Eastern Pacific, just below Baja California. Key message: Satellites give us a new perspective of our planet. Student Challenge: Study the large image of the Earth. What interesting features can you find? Do you see a hurricane?|
