摘要

About twice as much Western Hemisphere data from the Japan Aerospace Exploration Agency's Advanced Land Observing Satellite (ALOS) will be available under a new bilateral arrangement that uses NASA's Tracking and Data Relay Satellite System to download observations by the Japanese spacecraft. The L-band synthetic aperture radar on the satellite, called Palsar, measures changes in the surface ice sheets, forest cover, flooding, earthquakes and the like. The Alaska Satellite Facility will process and distribute data from the instrument, which will allow scientists "to see very small changes in surface elevation associated with the build-up and release of strain in seismic zones over virtually the entire area of the Americas, with measurements made as often as every 46 days," says Craig Dobson, natural hazards program manager in NASA's Earth Science Div. "Scientists also will be able to monitor seasonal changes in groundwater resources."
