Determination of Harmonic Parameters with Temporal Variations: An Enhanced Harmonic Analysis Algorithm and Application to Internal Tidal Currents in the South China Sea
(American Meteorological Society, 2018)AbstractAs an effective tool to distinguish different tidal components, classical tidal current harmonic analysis has been widely used to obtain harmonic parameters of internal tidal currents. However, harmonic parameters ... -
Quality Control of Surface Wind Observations in Northeastern North America. Part II: Measurement Errors
(American Meteorological Society, 2017)AbstractA quality control (QC) process has been developed and applied to an observational database of surface wind speed and wind direction in northeastern North America. The database combines data from three datasets of ... -
Fine Structure, Instabilities, and Turbulence in the Lower Atmosphere: High-Resolution In Situ Slant-Path Measurements with the DataHawk UAV and Comparisons with Numerical Modeling
(American Meteorological Society, 2017)AbstractA new platform for high-resolution in situ measurements in the lower troposphere is described and its capabilities are demonstrated. The platform is the small GPS-controlled DataHawk unmanned aerial system (UAS), ... -
Quality Control of Surface Wind Observations in Northeastern North America. Part I: Data Management Issues
(American Meteorological Society, 2017)AbstractA quality control (QC) process has been developed and implemented on an observational database of surface wind speed and direction in northeastern North America. The database combines data from 526 land stations ... -
Estimating Range-Dependent Evaporation Duct Height
(American Meteorological Society, 2017)AbstractThe refractivity from clutter (RFC) technique has been proved to be an effective way to estimate atmospheric duct structure. An important issue for RFC is how to make the estimate more robust, especially in ... -
Untitled
(American Meteorological Society, 2016)AbstractSpectral and structure function methods are implemented to compute the dissipation rate ε from broadband, diverging-beam acoustic Doppler current profiler (ADCP) data collected at four sites in a high-flow tidal ... -
Lidar Method to Estimate Emission Rates from Extended Sources
(American Meteorological Society, 2016)AbstractPollutant emissions to the atmosphere commonly derive from nonpoint sources that are extended in space. Such sources may contain area, volume, line, or a combination of emission types. Currently, point measurements, ... -
Ceilometer-Based Analysis of Shanghai’s Boundary Layer Height (under Rain- and Fog-Free Conditions)
(American Meteorological Society, 2017)AbstractTo investigate the boundary layer dynamics of the coastal megacity Shanghai, China, backscatter data measured by a Vaisala CL51 ceilometer are analyzed with a modified ideal curve fitting algorithm. The boundary ... -
Measuring the Marine Soundscape of the Indian Ocean with Southern Elephant Seals Used as Acoustic Gliders of Opportunity
(American Meteorological Society, 2016)AbstractThe underwater ambient sound field contains quantifiable information about the physical and biological marine environment. The development of operational systems for monitoring in an autonomous way the underwater ... -
Parameters of Cloud Ice Particles Retrieved from Radar Data
(American Meteorological Society, 2017)AbstractThe mean axis ratio (length/width) and the degree of orientation of cloud ice particles are retrieved from radar differential reflectivity (ZDR) and the copolar correlation coefficient (?hv) measured with the S-band ... -
A Comparative Analysis of Data Derived from Orbiting MSU/AMSU Instruments
(American Meteorological Society, 2016)AbstractSpencer and Christy of the University of Alabama in Huntsville (UAH) recently introduced a new method to process MSU/AMSU satellite brightness temperature data with their version 6 (v6) data. A comparison of UAH ... -
Comparison and Validation of Acoustic Response Models for Wind Noise Reduction Pipe Arrays
(American Meteorological Society, 2016)AbstractThe detection capability of the infrasound component of the International Monitoring System (IMS) is tightly linked to the performance of its wind noise reduction systems. The wind noise reduction solution implemented ... -
Development of a Flexible, Extendable, and Low-Cost Control Unit for Surface Drifters
(American Meteorological Society, 2017)AbstractAn extensible, low-cost drifter control unit (VELELLA) design is presented, developed for use in drifters that are deployed in inland water bodies or near-coast regions. The control unit is custom built from basic ... -
Data Analysis of Upper Atmosphere Temperature Detected by Sounding Rockets in China
(American Meteorological Society, 2017)AbstractSounding rockets launched by China have collected data on the upper atmosphere for nearly 50 years. In this work, the data accuracy and variable characteristics of upper atmosphere temperature data, gathered at ... -
A 10-Year Comparison of Water Levels Measured with a Geodetic GPS Receiver versus a Conventional Tide Gauge
(American Meteorological Society, 2016)AbstractA standard geodetic GPS receiver and a conventional Aquatrak tide gauge, collocated at Friday Harbor, Washington, are used to assess the quality of 10 years of water levels estimated from GPS sea surface reflections. ... -
