Estimation of a Humidity Profile Using Turbulence Echo Characteristics
Publisher: American Meteorological Society
Abstract: This paper is concerned with the development of a new stratosphere?troposphere radar technique for determining a height profile of specific humidity (q) by using characteristics of clear-air echoes in the troposphere. ...
Measurement of Atmospheric Aspect Sensitivity Using Coherent Radar Imaging after Mitigation of Radar Beam Weighting Effect
Publisher: American Meteorological Society
Abstract: he aspect angle, a measurement of the aspect sensitivity of atmospheric refractivity irregularities, was estimated with multiple-receiver coherent radar imaging (CRI) of very high frequency (VHF) atmospheric radar. Two CRI ...
Measurements of Detailed Temperature Profiles within the Radar Range Gate Using the Range Imaging Technique
Publisher: American Meteorological Society
Abstract: The present study applies the range imaging (RIM) technique to radio acoustic sounding system (RASS) measurements in an attempt to improve the vertical resolution of temperature profiles obtained by RASS measurements. When ...
Continuous Humidity Monitoring in a Tropical Region with the Equatorial Atmosphere Radar
Publisher: American Meteorological Society
Abstract: A radar remote sensing technique that estimates humidity profiles using a wind profiler is applied to the equatorial atmosphere radar (EAR) to monitor detailed humidity variations in tropical regions. Turbulence echo power ...
Measurement of Range-Weighting Function for Range Imaging of VHF Atmospheric Radars Using Range Oversampling
Publisher: American Meteorological Society
Abstract: ultifrequency range imaging (RIM) used with the atmospheric radars at ultra- and very high-frequency (VHF) bands is capable of retrieving the power distribution of the backscattered radar echoes in the range direction, ...
Estimation and Comparison of Horizontal Winds Using Various Spectral Estimation Methods on Profiler Radars
Publisher: American Meteorological Society
Abstract: he lower atmospheric wind profiles are obtained by the postset beam steering (PBS) technique on middle and upper (MU) atmosphere radar data. The Capon beamformer is used to improve the beam synthesizing in the desired ...
The Variational Assimilation Method for the Retrieval of Humidity Profiles with the Wind-Profiling Radar
Publisher: American Meteorological Society
Abstract: Recently, a humidity estimation technique was developed by using the turbulence echo characteristics detected with a wind-profiling radar. This study is concerned with improvement of the retrieval algorithm for delineating ...
