Latest Interferometric synthetic aperture radar Stories
Satellite radar data are being used to map Earth’s vital resources. The latest advances and applications of the POLinSAR remote sensing technique were highlighted at a conference held last week.
In a new report published in the journal Geophysical Research Letters, two scientists showed they may now be able to detect signs of an impending volcanic eruption by analyzing satellite imagery.
Archived radar data from the Envisat mission are playing an important role in mapping landslides in Switzerland.
Archived data from the Envisat satellite show that the volcanic island of Santorini has recently displayed signs of unrest. Even after the end of its mission, Envisat information continues to be exploited for the long-term monitoring of volcanoes.
Researchers studying the highest mountain range in the continental United States have been able to detect the rate at which it is growing and perhaps how old the mountains that are found there using new technology from space.
From the highest peak in the continental United States, Mt. Whitney at 14,000 feet in elevation, to the 10,000-foot-peaks near Lake Tahoe, scientific evidence from the University of Nevada, Reno shows the entire Sierra Nevada mountain range is rising at the relatively fast rate of 1 to 2 millimeters every year.
The importance of global and frequent data coverage of volcanoes was highlighted in a recent article published in Science. Satellites are finding that volcanoes previously thought to be dormant are showing signs of unrest.
