L-Band InSAR Penetration Depth Experiment, North Slope Alaska

L-Band InSAR Penetration Depth Experiment, North Slope Alaska

Since the first spacecraft-based synthetic aperture radar (SAR) mission NASA’s SEASAT in 1978 radars have been flown in Low Earth Orbit (LEO) by other national space agencies including the Canadian Space Agency, European Space Agency, India Space Research Organization and the Japanese Aerospace Exploration Agency. Improvements in electronics, miniaturization and production have allowed for the ...

The 2004 North Slope of Alaska Arctic Winter Radiometric Experiment: Overview and Recent Results

Accurate measurements of water vapor in the Arctic winter, either in situ or remote, are difficult to achieve. These measurements are important to studies in infrared radiative transfer. To focus on measurements during cold temperatures (< 20oC) and low amounts of vapor (Precipitable Water Vapor, 5 mm), an Intensive Operating Period (IOP) was conducted at the U.S. Department of Energy’s Atmosph...

Penetration depth of interferometric syntheticsaperture radar signals in snow and ice

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...
