Evaluation of the Performance Characteristics of the Lightning Imaging Sensor
(American Meteorological Society, 2019)AbstractThe Lightning Imaging Sensor (LIS) that was on board the Tropical Rainfall Measuring Mission (TRMM) satellite captured optical emissions produced by lightning. In this work, we quantify and evaluate the LIS performance ... -
Wind Direction Measurements on Moored Coastal Buoys
(American Meteorological Society, 2019)AbstractWind direction measurements from anchored floating objects (buoys) are disturbed by the movement of an agitated sea surface. This article describes corrected wind direction measurements that account for a rotated ... -
Correction and Accuracy of High- and Low-Resolution CTD Data from Animal-Borne Instruments
(American Meteorological Society, 2019)AbstractMost available CTD Satellite Relay Data Logger (CTD-SRDL) profiles are heavily compressed before satellite transmission. High-resolution profiles recorded at the sampling frequency of 0.5 Hz are, however, available ... -
Tropical Cyclone Rain Retrievals from FY-3B MWRI Brightness Temperatures Using the Goddard Profiling Algorithm (GPROF)
(American Meteorological Society, 2019)AbstractThis study focuses on the tropical cyclone rainfall retrieval using FY-3B Microwave Radiation Imager (MWRI) brightness temperatures (Tbs). The GPROF, a fully parametric approach based on the Bayesian scheme, is ... -
Swell and Wind Wave Inversion Using a Single Very High Frequency (VHF) Radar
(American Meteorological Society, 2019)AbstractA hybrid, empirical radar wave inversion technique that treats swell and wind waves separately is presented and evaluated using a single 48-MHz radar unit and in situ wave measurements. This hybrid approach greatly ... -
On the Importance of Statistical Homogeneity to the Scaling of Rain
(American Meteorological Society, 2019)AbstractScaling studies of rainfall are important for the conversion of observations and numerical model outputs among all the various scales. Two common approaches for determining scaling relations are the Fourier transform ... -
Wind Turbine Clutter Mitigation via Nonconvex Regularizers and Multidimensional Processing
(American Meteorological Society, 2019)AbstractThis paper generalizes a previous formulation of signal separation problem for dynamic wind turbine clutter mitigation at weather radar systems. In this modified formulation, we use nonconvex regularizers together ... -
Decadal Sea Level Variability in the Pacific Ocean: Origins and Climate Mode Contributions
(American Meteorological Society, 2019)AbstractSea level changes within wide temporal?spatial scales have great influence on oceanic and atmospheric circulations. Efforts have been made to identify long-term sea level trend and regional sea level variations on ... -
A New Criterion to Improve Operational Drizzle Detection with Ground-Based Remote Sensing
(American Meteorological Society, 2019)AbstractLight shallow precipitation in the form of drizzle is one of the mechanisms for liquid water removal, affecting cloud lifetime and boundary layer dynamics and thermodynamics. The early formation of drizzle drops ... -
Improved Multifractal Fusion Method to Blend SMOS Sea Surface Salinity Based on Semiparametric Weight Function
(American Meteorological Society, 2019)AbstractThe multifractal fusion method has proved to be an effective algorithm to mitigate the noise of the sea surface salinity (SSS) of Soil Moisture Ocean Salinity (SMOS) mission. However, the traditional nonparametric ... -
W-Band (95 GHz) Radar Attenuation in Tropical Stratiform Ice Anvils
(American Meteorological Society, 2019)AbstractAttenuation of the W-band (95 GHz) radar signal by atmospheric ice particles has long been neglected in cloud microphysics studies. In this work, 95-GHz airborne multibeam cloud radar observations in tropical ... -
Impacts of Partly Cloudy Pixels on Shortwave Broadband Irradiance Computations
(American Meteorological Society, 2019)AbstractBecause of the limitation of the spatial resolution of satellite sensors, satellite pixels identified as cloudy are often partly cloudy. For the first time, this study demonstrates the bias in shortwave (SW) broadband ... -
Comparison of Oceanic Multisatellite Precipitation Data from Tropical Rainfall Measurement Mission and Global Precipitation Measurement Mission Datasets with Rain Gauge Data from Ocean Buoys
(American Meteorological Society, 2019)AbstractThree satellite-derived precipitation datasets [the Tropical Rainfall Measuring Mission Multisatellite Precipitation Analysis (TMPA) dataset, the NOAA Climate Prediction Center morphing technique (CMORPH) dataset, ... -
Performance Characteristics of “Spotter,” a Newly Developed Real-Time Wave Measurement Buoy
(American Meteorological Society, 2019)AbstractThe Spotter is a low-cost, real-time, solar-powered wave measurement buoy that was recently developed by Spoondrift Technologies, Inc. (Spoondrift). To evaluate the data quality of the Spotter device, we performed ... -
On the Long-Wavelength Validation of the SWOT KaRIn Measurement
(American Meteorological Society, 2019)AbstractThe Surface Water and Ocean Topography (SWOT) mission will measure the sea surface height (SSH) using a Ka-band radar interferometer (KaRIn) over a swath off the nadir of the satellite tracks. The mission requires ... -
An Automated Detection Methodology for Dry Well-Mixed Layers
(American Meteorological Society, 2019)AbstractThe intense surface heating over arid land surfaces produces dry well-mixed layers (WML) via dry convection. These layers are characterized by nearly constant potential temperature and low, nearly constant water ... -
Detection of Ground Clutter for Dual-Polarization Weather Radar Using a Novel 3D Discriminant Function
