(American Meteorological Society, 2018)AbstractResearchers now have the benefit of an unprecedented suite of space- and ground-based sensors that provide multidimensional and multiparameter precipitation information. Motivated by NASA?s Global Precipitation ... -
A Coupled System for Investigating the Physics of Wave–Ice Interactions
(American Meteorological Society, 2018)AbstractA coupled model system has been developed to investigate the physics of wave attenuation and ice edge retreat in the marginal ice zone (MIZ) at small scales [O(m)]. A phase-dependent finite-volume/finite-difference ... -
Retrieving Mean Temperature of Atmospheric Liquid Water Layers Using Microwave Radiometer Measurements
(American Meteorological Society, 2018)AbstractA remote sensing method to retrieve the mean temperature of cloud liquid using ground-based microwave radiometer measurements is evaluated and tested by comparisons with direct cloud temperature information inferred ... -
Assessment of Doppler Radar Radial Wind Observation Quality from Different Echo Sources for Assimilation during the Sydney 2014 Forecast Demonstration Project
(American Meteorological Society, 2018)AbstractA new quality control system, primarily using a naïve Bayesian classifier, has been developed to enable the assimilation of radial velocity observations from Doppler radar. The ultimate assessment of this system ... -
Application of the EMD Method to River Tides
(American Meteorological Society, 2018)AbstractA lot of tidal phenomena, including river tides, tides in ice-covered bays, and internal tides in fjords, are nonstationary. These tidal processes present a severe challenge for the conventional tidal analysis ... -
Modeling of Mineral Dust Emissions with a Weibull Wind Speed Distribution Including Subgrid-Scale Orography Variance
(American Meteorological Society, 2018)AbstractThe modeling of mineral dust emissions requires an extensive knowledge of the wind speed close to the surface. In regional and global models, Weibull distributions are often used to better represent the subgrid-scale ... -
Collection of Gas-Tight Water Samples from the Bottom of the Challenger Deep
(American Meteorological Society, 2018)AbstractA new gas-tight pair sampler was designed for the collection of gas-tight fluid samples from the hadal zone. The sampler uses two titanium bottles and one sampling valve to collect two samples at once. The sampler ... -
A Simple and Effective Method for Separating Meteorological from Nonmeteorological Targets Using Dual-Polarization Data
(American Meteorological Society, 2018)AbstractTo satisfy the needs of the meteorological and aeroecological communities wanting a simple but effective way of flagging each other?s unwanted echo for a variety of different operational radar systems, we evaluated ... -
TRMM Version 8 Reprocessing Improvements and Incorporation into the GPM Data Suite
(American Meteorological Society, 2018)AbstractThe National Aeronautics and Space Administration (NASA) has always included data reprocessing as a major component of every science mission. A final reprocessing is typically a part of mission closeout (known as ... -
Simulating Radiative Fluxes through Southeastern Pacific Stratocumulus Clouds during VOCALS-REx
(American Meteorological Society, 2018)ABSTRACTTime series of solar and thermal infrared radiative flux profiles are simulated with the Rapid Radiative Transfer Model (RRTM) using a hierarchy of constraints from radar reflectivity and passive microwave cloud ... -
