Alaska Satellite Facility


SAR, used to create the majority of the imagery available in the ASF archive, is one of the power tools of remote sensing. SAR bounces a microwave radar signal off the Earth's surface to detect physical properties.

Unlike optical technology, SAR can "see" through darkness, clouds, and rain, detecting changes in habitat, levels of water and moisture, effects of natural or human disturbance, and changes in the Earth’s surface after events such as earthquakes or sinkhole openings. SAR been used in a wide range of research, from chronicling the calving of enormous Antarctic icebergs, to tracking the paths of oil spills into sensitive marshes, to mapping the wetlands of Alaska.
