This finer granularity eases the browsing of the retrieval result. The approach supports multimedia and networked IR since multimedia documents are composed of other objects and networks combine several colle...

Freeze/Thaw (F/T) surface state retrieval is important to further understand hydrological patterns and climate change. This article investigates the use of Earth-reflected Global Positioning System (GPS) L-band signals as collected by National Aeronautics Space Administration NASA’s Cyclone Navigation Satellite (CYGNSS) mission for F/T over a target area in South America, covering Andes Mountai...
