Microwave and Visible satellite image of Hurricane Ike on September 7, 2008. The image shows how the passive microwave sensor receives less radiation from regions of heavy rainfall (near the center of the hurricane in the eyewall, in the intense rainbands, and in the strong convection along the south coast of Haiti). In regions where there is not heavy precipitation (eye of Ike, most of the image outside the hurricane), the blue colors show higher amounts of microwave radiation reaching the sensor. Because microwave radiation from Earth's surface has a similar wavelength to the diameter of

Unformatted text preview: raindrops, it is “blocked” by heavy rain and less of it reaches the passive sensor. This image also demonstrates how microwave data like this come from low-earth orbit satellites that see “swaths” of Earth's surface as they orbit. Outside of the swath, visible imagery from a geostationary satellite is displayed. This sensor detects radiation emitted in the visible range of the EM spectrum (also in a passive manner) and is useful for showing clouds during daylight hours....
