Optimization of Sea Surface Current Retrieval Using a Maximum Cross-Correlation Technique on Modeled Sea Surface Temperature
(American Meteorological Society, 2017)AbstractUsing sea surface temperature from satellite images to retrieve sea surface currents is not a new idea, but so far its operational near-real-time implementation has not been possible. Validation studies are too ... -
Influence of Pycnocline Smoothing and Subgrid-Scale Variability of Density Profiles on the Determination of Mixed Layer Depth
(American Meteorological Society, 2017)AbstractThis study investigates how pycnocline smoothing and subgrid-scale variability of density profiles influence the determination of the mixed layer depth (MLD) in the global ocean, and applies the results of analysis ... -
Sea Surface Scanner (S3): A Catamaran for High-Resolution Measurements of Biogeochemical Properties of the Sea Surface Microlayer
(American Meteorological Society, 2017)AbstractThis paper describes a state-of-the-art research catamaran to investigate processes such as air?sea gas exchange, heat exchange, surface blooms, and photochemistry at the sea surface microlayer (SML) with high-resolution ... -
A W-Band Radar–Radiometer System for Accurate and Continuous Monitoring of Clouds and Precipitation
(American Meteorological Society, 2017)AbstractA new 94-GHz frequency-modulated continuous wave (FMCW) Doppler radar?radiometer system [Jülich Observatory for Cloud Evolution (JOYCE) Radar?94 GHz (JOYRAD-94)] is presented that is suitable for long-term continuous ... -
An Approach to Simulate the Effects of Antenna Patterns on Polarimetric Variable Estimates
(American Meteorological Society, 2017)AbstractOne of the main challenges of using phased array radar for weather observations is the implementation of dual polarization with acceptable errors of polarimetric variable estimates. This is because the differences ... -
An Inverse Problem Approach for the Retrieval of Ice Particle Mass from In Situ Measurements
(American Meteorological Society, 2017)AbstractMass?dimensional relationships have been published for decades to characterize the microphysical properties of ice cloud particles. Classical retrieval methods employ a simplifying assumption that restricts the ... -
Analysis and Mitigation of Striping Noise in Two Water Vapor Sounding Channels of Global Precipitation Measurement (GPM) Microwave Imager
(American Meteorological Society, 2017)AbstractThe Global Precipitation Measurement (GPM) Microwave Imager (GMI) plays an important role in monitoring global precipitation. In this study, an along-track striping noise is found in GMI observations of brightness ... -
Application of Surface Spline Interpolation in Inversion of Bottom Friction Coefficients
(American Meteorological Society, 2017)AbstractA new method for the inversion of bottom friction coefficients (BFCs) in a two-dimensional tidal model is proposed in this study. In this method, the field of BFCs is constructed by interpolating values at independent ... -
A Coupled Circulation–Wave Model for Numerical Simulation of Storm Tides and Waves
(American Meteorological Society, 2017)AbstractThe Stevens Institute of Technology Estuarine and Coastal Ocean Model (sECOM) is coupled here with the Mellor?Donelan?Oey (MDO) wave model to simulate coastal flooding due to storm tides and waves. sECOM is the ... -
Untitled
(American Meteorological Society, 2017)AbstractData collected with acoustic Doppler current profilers installed on CTD rosettes and lowered through the water column [lowered ADCP (LADCP) systems] are routinely used to derive full-depth profiles of ocean velocity. ... -
Untitled
(American Meteorological Society, 2017)AbstractThe performance of the OTT second-generation Particle Size Velocity (PARSIVEL2) laser weather sensor is evaluated by comparing it with a collocated two-dimensional video disdrometer (2DVD) and rain gauges using ... -
Sea Surface Wind Correction Using HF Ocean Radar and Its Impact on Coastal Wave Prediction
(American Meteorological Society, 2017)AbstractBoth wind speeds and wind directions are important for predicting wave heights near complex coastal areas, such as small islands, because the fetch is sensitive to the wind direction. High-frequency (HF) radar can ... -
Determining Mixing Rates from Concurrent Temperature and Velocity Measurements
(American Meteorological Society, 2017)AbstractOcean mixing has historically been estimated using Osborn?s model by measuring the rate of dissipation of turbulent kinetic energy ? and the background density stratification N while assuming a value of the flux ... -
Low-Frequency Seismic Node Based on Molecular-Electronic Transfer Sensors for Marine and Transition Zone Exploration
(American Meteorological Society, 2017)AbstractA self-contained seismic station that has a modular structure adjustable to different operational conditions?like onshore, offshore to 500-m depth, and at transition zones?has been developed and field tested. The ... -
Wind Tunnel Results for a Distributed Flush Airdata System
(American Meteorological Society, 2017)AbstractThe multihole probe (MHP) is an effective instrument for relative wind measurements from small unmanned aircraft systems (sUAS). Two common drawbacks for the integration of commercial MHP systems into low-cost sUAS ... -
