Ocean Vector Winds in Storms from the SMAP L-Band Radiometer

Our paper discusses the unique capability of the SMAP L-band radiometer to measure strong winds in tropical and extratropical cyclones. There is no significant degradation in rain. INTRODUCTION AND OUTLINE The Soil Moisture Active Passive Mission SMAP (Entekhabi et al., 2010) was launched in January 2015 and has been providing science data since April 2015. Though designed to measure soil moist...

Scanning L-band Active Passive (slap)—recent Results from an Airborne Simulator for Smap

Scanning L-band Active Passive (SLAP) is a recently-developed NASA airborne instrument specially tailored to simulate the new Soil Moisture Active Passive (SMAP) satellite instrument suite [1]. SLAP conducted its first test flights in December, 2013 and participated in its first science campaign—the IPHEX ground validation campaign of the GPM mission—in May, 2014. This paper will present result...

Depth Estimation of Submerged Aquatic Vegetation in Clear Water Streams Using Low-Altitude Optical Remote Sensing

UAVs and other low-altitude remote sensing platforms are proving very useful tools for remote sensing of river systems. Currently consumer grade cameras are still the most commonly used sensors for this purpose. In particular, progress is being made to obtain river bathymetry from the optical image data collected with such cameras, using the strong attenuation of light in water. No studies have...

Depth from Scattering

Light power is a ected when it crosses the atmosphere; there is a simple, albeit non-linear, relationship between the radiance of an image at any given wavelength and the distance between object and viewer. This phenomenon is called atmospheric scattering and has been extensively studied by physicists and meterologists. We present the rst analysis of this phenomenon from an image understanding ...
