The long-term goal of this research effort is to investigate the possibility of obtaining quantitative information about the near-surface wind field and perhaps other parameters that characterize the Marine Atmospheric Boundary Layer (MABL) from an analysis of Synthetic Aperture Radar (SAR) imagery. Because of its potential for yielding such information in the form of high-resolution imagery, t...

The long-term goal of the research effort to be described in this paper is to investigate the possibility of obtaining quantitative information about the near-surface wind field and perhaps other parameters that characterize the Marine Atmospheric Boundary Layer (MABL) from an analysis of Synthetic Aperture Radar (SAR) imagery.

This paper presents a novel combination of synchronous, large coverage marine radar, calibrated pulsed Doppler radar, and video remote sensing observations from a nearshore field site. The data enable the analysis of the evolution and characteristics of the remotely observed signals from surf zone waves. The combination of different remote sensors allows a better discrimination between breaking...

A planar microstrip ring resonator structure on alumina was developed using the commercial FEM software COMSOL. Design parameters were evaluated, eventually leading to an optimized design of a miniaturized microwave gas sensor. The sensor was covered with a zeolite film. The device was successfully operated at around 8.5 GHz at room temperature as a humidity sensor. In the next step, an additio...

The estimation of snow water equivalent (SWE) from passive microwave sensors remains a formidable challenge primarily due to the non-unique nature of the microwave scattering signatures over snow cover surfaces. Ideally, there is a straightforward relationship between the volume of snow crystals present in the snow pack, and hence, SWE or snow depth, and the degree of microwave scattering by ic...

Active microwave sensors, especially high-frequency radar systems, are highly sensitive to snow pack parameters, including Snow Water Equivalent (SWE), which is a crucial parameter in the studies of hydrology and climatology. For example, studies using Ku-band observations from scatterometer QuickSCAT and POLSCAT have shown significant radar backscattering responses on SWE variations. It has be...

Asparagus spears are sensitive to thermal treatments. Lengthy pasteurization at elevated temperatures may cause severe thermal degradation. In this research we explored the application of short-time microwave pasteurization for pickled asparagus in glass bottles and studied the effect of this process on the textural quality of the products in comparison with the conventional hot-water pasteuriz...

Measurements of real (ε′) and imaginary (ε’’) parts of the complex dielectric constant (ε*) of soil with varied moisture content have been made at 9.44 GHz using infinite sample method. The electrical properties of dry soil samples are found to be in good agreement with the earlier work. The values of ε′ and ε′′ first increase slowly and then increase rapidly with moisture content. From this da...

Microwave testing has the advantage of detecting surface and sub-surface flaws and anomalies under coatings, paint or dirt. Thus, major application of microwave sensors is imaging to determine the shape, size, and location of buried flaws using scattered field measurements. A typical microwave system consists of transmitting and receiving antennas and requires that both sides of the material un...

Using the Advanced Microwave Scanning Radiometer sensor (AMSR-E), winter (October to May) sea ice area flux is estimated for the main channels of the Canadian Arctic Archipelago, Baffin Bay and Fram Strait. The transport through Fram Strait is estimated at 533,000 km 2 and 635,000 km 2 for the winter of 2002/03 and 2003/04 which is below the 24-year average of 754,000 km 2 obtained by Kwok et a...
