(American Meteorological Society, 2004)Numerical simulation can be used for optimizing radar imaging techniques because it allows the accuracy of various techniques to be studied. A simulation of atmospheric conditions by using scatterers in a 3D volume was ... -
Relationship between ERS Scatterometer Measurement and Integrated Wind and Wave Parameters
(American Meteorological Society, 2004)Potential effects of environmental parameters such as sea state or atmospheric boundary layer stability on the normalized radar cross section (NRCS) measured by spaceborne sensors have been investigated for a long time. ... -
Effect of Nonuniform Beam Filling on the Propagation of Radar Signals at X-Band Frequencies. Part II: Examination of Differential Phase Shift
(American Meteorological Society, 2004)An analysis of the effects of nonuniform beam filling on the measurement of the propagation phase shift for X-band radar is presented. An analytical expression is derived for the measured differential phase shift. It is ... -
Uncertainties in Estimates of Reynolds Stress and TKE Production Rate Using the ADCP Variance Method
(American Meteorological Society, 2004)The use of acoustic Doppler current profilers (ADCPs) to measure turbulent parameters via the variance method involves uncertainties due to instrument noise and flow-related errors in measurement. For weak flows, the ... -
Errors in Second Moments Estimated from Monostatic Doppler Sodar Winds. Part II: Application to Field Measurements
(American Meteorological Society, 1986)In this paper we use the theoretical results presented in Part I of this paper to correct turbulence parameters derived from monostatic sodar wind measurements in an attempt to improve the statistical comparisons made with ... -
Networked Acoustic Modems for Real-Time Data Delivery from Distributed Subsurface Instruments in the Coastal Ocean: Initial System Development and Performance
(American Meteorological Society, 2004)Results are reported from field tests of networked acoustic modems used for wireless real-time delivery of oceanographic measurements from a distributed array of subsurface instruments in coastal waters. The network ... -
Correction of Motional Electric Field Measurements for Galvanic Distortion
(American Meteorological Society, 2004)Interactions between motional electric fields and lateral gradients in electrical conductivity (e.g., seafloor topography) produce boundary electric charges and galvanic (i.e., noninductive) secondary electric fields that ... -
A Method for Obtaining the Mean Transports of Ocean Currents by Combining Isopycnal Float Data with Historical Hydrography
(American Meteorological Society, 2004)This article presents a method for obtaining the mean structure of the temperature, specific volume anomaly, and velocity of an ocean current, using isopycnal float data combined with gravest empirical mode (GEM) fields ... -
Modeling the Spatial Response of the Airfoil Shear Probe Using Different Sized Probes
(American Meteorological Society, 2004)The airfoil shear probe is the only robust sensor currently available for measuring the rate of dissipation of kinetic energy in the ocean. The wavenumber (or spatial) resolution of the shear probe is determined by its ... -
