The electromagnetic bias (EM) is a critical error term in sea surface height estimation from satellite radar altimetry. At present the EM bias models used in current altimetry missions are empirically based and globally-averaged functions of the altimetermeasured signi cant wave height and wind speed alone. Recent studies have shown that a reduction in the EM bias error variance can be achieved...

aBstr aCt. Seamounts are active or extinct undersea volcanoes with heights exceeding ~ 100 m. They represent a small but significant fraction of the volcanic extrusive budget for oceanic seafloor and their distribution gives information about spatial and temporal variations in intraplate volcanic activity. In addition, they sustain important ecological communities, determine habitats for fish, ...

Digital elevation models of glaciated terrain produced by the NASA/Jet Propulsion Laboratory (JPL) airborne interferometric synthetic-aperture radar (InSAR) instrument in Greenland and Alaska at the C(5.6 cm wavelength) and L-band (24-cm) frequencies were compared with surface elevation measured from airborne laser altimetry to estimate the phase center of the interferometric depth, or penetrat...

17 Remote sensing (RS) data are an alternative to in-situ hydrometeorological data in 18 remote and poorly monitored areas and are increasingly used in hydrological 19 modeling. This study presents a lumped, conceptual, river basin water balance 20 modeling approach based entirely on RS data: precipitation was obtained from the 21 Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precip...
