On Nano Ellipsoid Transport and Deposition in the Lung First Bifurcation Effect of Slip Correction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent rapid development of industrial usage of carbon nanotubes (CNTs) has raised health concerns as these engineered elongated particles resemble the appearance of asbestos, which is a wellknown inhalation hazard. While ...
Measurement of Attenuation by a Dual-Radar Method: Concept and Error Analysis
Publisher: American Meteorological Society
Abstract: The authors describe a method for the measurement of specific attenuation using two radars operating at virtually the same wavelength at which the attenuation is desired. Use of the same wavelength avoids confounding between ...
Measurement of Attenuation at C Band in a Convective Storm by a Dual-Radar Method
Publisher: American Meteorological Society
Abstract: Retrievals of specific attenuation at 5.5-cm wavelength from dual-radar observations of a summer convective storm in Florida are presented. The retrieved specific attenuation is positive except in regions near the radars ...
Measurements of Ocean Surface Backscattering Using an Airborne 94-GHz Cloud Radar—Implication for Calibration of Airborne and Spaceborne W-Band Radars
Publisher: American Meteorological Society
Abstract: Backscattering properties of the ocean surface have been widely used as a calibration reference for airborne and spaceborne microwave sensors. However, at millimeter-wave frequencies, the ocean surface backscattering ...
A Robust Dual-Frequency Radar Profiling Algorithm
Publisher: American Meteorological Society
Abstract: n this study, an algorithm to retrieve precipitation from spaceborne dual-frequency (13.8 and 35.6 GHz, or Ku/Ka band) radar observations is formulated and investigated. Such algorithms will be of paramount importance in ...
Measurements and Simulations of Nadir-Viewing Radar Returns from the Melting Layer at X and W Bands
Publisher: American Meteorological Society
Abstract: Simulated radar signatures within the melting layer in stratiform rain?namely, the radar bright band?are checked by means of comparisons with simultaneous measurements of the bright band made by the ER-2 Doppler radar ...
The Dual Wavelength Ratio Knee: A Signature of Multiple Scattering in Airborne Ku–Ka Observations
Publisher: American Meteorological Society
Abstract: eep convective systems observed by the High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) radar during the 2011 Midlatitude Continental Convective Clouds Experiment (MC3E) field campaign in Oklahoma provide the ...
A 94-GHz Cloud Radar System on a NASA High-Altitude ER-2 Aircraft
Publisher: American Meteorological Society
Abstract: The 94-GHz (W band) Cloud Radar System (CRS) has been developed and flown on a NASA ER-2 high-altitude (20 km) aircraft. The CRS is a fully coherent, polarimetric Doppler radar that is capable of detecting clouds and ...
Velocity–Azimuth Display Analysis of Doppler Velocity for HIWRAP
Publisher: American Meteorological Society
Abstract: he velocity?azimuth display (VAD) analysis technique established for ground-based scanning radar is applied to the NASA High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP). The VAD technique provides a mean ...
Airborne Radar Observations of Severe Hailstorms: Implications for Future Spaceborne Radar
Publisher: American Meteorological Society
Abstract: new dual-frequency (Ku and Ka band) nadir-pointing Doppler radar on the high-altitude NASA ER-2 aircraft, called the High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP), has collected data over severe thunderstorms ...
