On the Accuracy of Vaisala RS41 versus RS92 Upper-Air Temperature Observations
(American Meteorological Society, 2019)AbstractThe accuracy of Vaisala RS92 versus RS41 global radiosonde soundings, emphasizing stratospheric temperature, is assessed from January 2015 to June 2017 using ~311 500 RS92 and ~65 800 RS41 profiles and three different ... -
Using Sounder Data to Improve Cirrus Cloud Height Estimation from Satellite Imagers
(American Meteorological Society, 2019)AbstractModern polar-orbiting meteorological satellites provide both imaging and sounding observations simultaneously. Most imagers, however, do not have H2O and CO2 absorption bands and therefore struggle to accurately ... -

(American Meteorological Society, 2019)AbstractThe characteristics of microphysical processes of a severe winter storm that occurred on the Korean Peninsula on 12 December 2013 was studied in this work for the first time via X-band dual-polarization weather ... -
Resonance Scattering Detection Using the CSU–CHILL Dual-Wavelength, Dual-Polarization Radar
(American Meteorological Society, 2019)AbstractThe CSU?CHILL radar is a dual-wavelength, dual-polarization weather radar system operating at S and X band with coaxial beams. This radar system offers a unique environment to develop and/or validate algorithms ... -
Novel Data Assimilation Algorithm for Nearshore Bathymetry
(American Meteorological Society, 2019)AbstractIt can be expensive and difficult to collect direct bathymetry data for nearshore regions, especially in high-energy locations where there are temporally and spatially varying bathymetric features like sandbars. ... -
Correcting Himawari-8 Advanced Himawari Imager Data for the Production of Vivid True-Color Imagery
(American Meteorological Society, 2019)AbstractObservations of top-of-atmosphere radiances from the Advanced Himawari Imager (AHI) blue, green, and red spectral bands can be used to produce high-temporal-resolution, true-color imagery at 1-km spatial resolution ... -
Corrections for Pumped SBE 41CP CTDs Determined from Stratified Tank Experiments
(American Meteorological Society, 2019)AbstractSea-Bird Scientific SBE 41CP CTDs are used on autonomous floats in the global Argo ocean observing program to measure the temperature and salinity of the upper ocean. While profiling, the sensors are subject to ... -
Estimating Four-Dimensional Internal Wave Spectrum in the Northern South China Sea
(American Meteorological Society, 2019)AbstractInternal waves can transfer energy from large-scale to microscale processes; however, the spectra of these waves remain poorly known. A method that combines modal harmonic decomposition and maximum-likelihood method ... -
The 2016 CEOS Infrared Radiometer Comparison: Part II: Laboratory Comparison of Radiation Thermometers
(American Meteorological Society, 2019)AbstractTo ensure confidence, measurements carried out by imaging radiometers mounted on satellites require robust validation using ?fiducial quality? measurements of the same in situ parameter. For surface temperature ... -
Atmospheric Duct Detection Using Wind Profiler Radar and RASS
(American Meteorological Society, 2019)AbstractA method of detecting atmospheric ducts using a wind profiler radar (WPR) and a radio acoustic sounding system (RASS) is proposed. The method uses the RASS to measure the virtual temperature profile and calculate ... -
