The Estimation of the Total Freeboard of Arctic Sea Ice in Winter Using Passive Microwave Satellite Measurements
(American Meteorological Society, 2022)A method for estimating the total freeboard -
Evaluating Vertical Velocity Retrievals from Vertical Vorticity Equation Constrained Dual-Doppler Analysis of Real, Rapid-Scan Radar Data
(American Meteorological Society, 2022)Accurate vertical velocity retrieval from dual-Doppler analysis (DDA) is a long-standing problem of radar meteorology. Typical radar scanning strategies poorly observe the vertical component of motion, leading to large ... -
Performance Evaluation of Force Transducer for the Observation of Sediment Entrainment in Rapidly Varied Flows
(American Meteorological Society, 2022)Direct measurement of forces within the rough bed layer have been limited by previous spatial-averaging shear force studies. A highly sensitive force transducer assembled with a target sphere was used to measure and record ... -
Bayesian Classification of Nonmeteorological Targets in Polarimetric Doppler Radar Measurements
(American Meteorological Society, 2022)The latest established generation of weather radars provides polarimetric measurements of a wide variety of meteorological and nonmeteorological targets. While the classification of different precipitation types based on ... -
Experimental Confirmation of Stokes Drift Measurement by High-Frequency Radars
(American Meteorological Society, 2022)High-frequency radars (HFR) remotely measure ocean surface currents based on the Doppler shift of electromagnetic waves backscattered by surface gravity waves with one-half of the electromagnetic wavelength, called Bragg ... -
Static and Dynamic Performance of the RBRargo3 CTD
(American Meteorological Society, 2022)The static and dynamic performances of the RBR -
Acoustic Float Tracking with the Kalman Smoother
(American Meteorological Society, 2022)Acoustically tracked subsurface floats provide insights into ocean complexity and were first deployed over 60 years ago. A standard tracking method uses a least squares algorithm to estimate float trajectories based on ... -
Conditions for Reliable Divergence Estimates from Drifter Triplets
(American Meteorological Society, 2022)Horizontal velocity gradients of a flow field and the related kinematic properties (KPs) of divergence, vorticity, and strain rate can be estimated from dense drifter deployments, e.g., the spatiotemporal average divergence ... -
Improvement of the Ocean Mixed Layer Model via Large-Eddy Simulation and Inverse Estimation
(American Meteorological Society, 2022)The ocean mixed layer model (OMLM) is improved using the large-eddy simulation (LES) and the inverse estimation method. A comparison of OMLM (Noh model) and LES results reveals that underestimation of the turbulent kinetic ... -
Analytical and Residual Bootstrap Methods for Parameter Uncertainty Assessment in Tidal Analysis with Temporally Correlated Noise
(American Meteorological Society, 2022)Reconstructing tidal signals is indispensable for verifying altimetry products, forecasting water levels, and evaluating long-term trends. Uncertainties in the estimated tidal parameters must be carefully assessed to ... -
Impacts of Instrumented Bottom Frame on Flow and Turbulence Measurements
(American Meteorological Society, 2022)A series of laboratory experiments are carried out to demonstrate the impacts of instrumented bottom frame legs on flow and turbulence. The magnitudes of vertical velocity, turbulent kinetic energy, dissipation, and shear ... -
Deep Learning for Typhoon Intensity Classification Using Satellite Cloud Images
(2022)A tropical cyclone, also known as a typhoon, is one of the most destructive weather phenomena. Its intense cyclonic eddy circulations often cause serious damage to coastal areas. Accurate classification or prediction for ... -
Retrieval of Snow Water Equivalent by the Precipitation Imaging Package (PIP) in the Northern Great Lakes
(2022)Performance of the Precipitation Imaging Package (PIP) for estimating the snow water equivalent (SWE) is evaluated through a comparative study with the collocated National Oceanic and Atmospheric Administration National ... -
Radar Icing Algorithm: Algorithm Description and Comparison with Aircraft Observations
(2022)Detection of in-flight icing hazard is a priority of the aviation safety community. The “Radar Icing Algorithm” (RadIA) has been developed to indicate the presence, phase, and relative size of supercooled drops. This paper ... -
A Nonparametric, Data-Driven Approach to Despiking Ocean Surface Wave Time Series
(2022)We propose a methodology for despiking ocean surface wave time series based on a Bayesian approach to data-driven learning known as Gaussian process (GP) regression. We show that GP regression can be used for both robust ... -
A Geostationary Lightning Pseudo-Observation Generator Utilizing Low-Frequency Ground-Based Lightning Observations
(2021)Coincident Geostationary Lightning Mapper (GLM) and National Lightning Detection Network (NLDN) observations are used to build a generator of realistic lightning optical signal in the perspective to simulate Lightning ... -
A Note on the Depth of Sidelobe Contamination in Acoustic Doppler Current Profiles
(2022)Acoustic Doppler current profilers (ADCP) do not provide reliable water velocity measurements near the sea surface or bottom because acoustic sidelobe reflections from the boundary contaminate the Doppler velocity measurements. ... -
Sensitivity of Surface Currents to Bathymetry in a Partially Mixed Estuary with Applications to Inverse Modeling
(2022)An inversion technique was tested for estimating bathymetry from observations of surface currents in a partially mixed estuary, the mouth of the Columbia River (MCR). The methodology uses an iterative ensemble-based ... -
