Longwave Radiation Corrections for the OMNI Buoy Network
(2022)The inception of a moored buoy network in the northern Indian Ocean in 1997 paved the way for systematic collection of long-term time series observations of meteorological and oceanographic parameters. This buoy network ... -
Data Fusion of GEO FY-4A GIIRS and LEO Hyperspectral Infrared Sounders with Surface Observations: A Hong Kong Case Study
(2022)Hyperspectral infrared satellite observations from geostationary platforms allow for the retrieval of temperature and water vapor measurements with higher temporal and vertical resolution than was previously available. The ... -
Clustering of Climate Change Impacts on Ocean Waves in the Northwest Atlantic
(2022)The provision of reliable results from numerical wave models implemented over vast ocean areas can be considered as a time-consuming process. In this regard, the estimation of areas with maximum similarity in wave climate ... -
Direction Finding and Likelihood Ratio Detection for Oceanographic HF Radars
(2021)Previous work with simulations of oceanographic high-frequency (HF) radars has identified possible improvements when using maximum likelihood estimation (MLE) for direction of arrival; however, methods for determining the ... -
Solar Monitoring of the NEXRAD WSR-88D Network Using Operational Scan Data
(2022)Solar monitoring is a method in which solar interferences, recorded during operational scanning of a radar, are used to monitor antenna pointing, identify signal processor issues, track receiver chain stability, and check ... -
On the Misclassification of Dust as Cloud at an AERONET Site in the Sonoran Desert
(2022)Here we present retrievals of aerosol optical depth τ from an Aerosol Robotic Network (AERONET) station in the southeastern corner of California, an area where dust storms are frequent. By combining AERONET data with ... -
Accurate Absolute Measurements of Liquid Water Content (LWC) and Ice Water Content (IWC) of Clouds and Precipitation with Spectrometric Water Raman Lidar
(2022)A detailed description is given of how the liquid water content (LWC) and the ice water content (IWC) can be determined accurately and absolutely from the measured water Raman spectra of clouds. All instrumental and ... -
Fine-Scale Velocity Measurement on the Wirewalker Wave-Powered Profiler
(2022)The Wirewalker (WW) ocean-wave-powered vertical profiling system allows the collection of high-resolution oceanographic data due to its rapid profiling, hydrodynamically quiet operation, and long endurance. We have assessed ... -
The Effects of Heavy Precipitation on Polarimetric Radio Occultation (PRO) Bending Angle Observations
(2022)Following the successful launch of the Spanish PAZ mission the proof of concept experiment “Radio Occultation and Heavy Precipitation with PAZ” (ROHP-PAZ) started operating in May 2018. The ROHP-PAZ observations demonstrated ... -

A Statistical Interpolation Code for Ocean Analysis and Forecasting
(2022)We present a data assimilation package for use with ocean circulation models in analysis, forecasting, and system evaluation applications. The basic functionality of the package is centered on a multivariate linear statistical ... -
BOREAL—A Fixed-Wing Unmanned Aerial System for the Measurement of Wind and Turbulence in the Atmospheric Boundary Layer
(2022)An instrumentation package for wind and turbulence observations in the atmospheric boundary layer on an unmanned aerial vehicle (UAV) called BOREAL has been developed. BOREAL is a fixed-wing UAV built by BOREAL company, ... -
Rain Drop Size Distributions Estimated from NOAA Snow-Level Radar Data
(2022)Using NOAA’s S-band High-Power Snow-Level Radar (HPSLR), a technique for estimating the rain drop size distribution (DSD) above the radar is presented. This technique assumes the DSD can be described by a four parameter, ... -
Low Cloud Detection in Multilayer Scenes Using Satellite Imagery with Machine Learning Methods
(2022)The detection of multilayer clouds in the atmosphere can be particularly challenging from passive visible and infrared imaging radiometers since cloud boundary information is limited primarily to the topmost cloud layer. ... -
Observing Profiles of Derived Kinematic Field Quantities Using a Network of Profiling Sites
(2022)Observations of thermodynamic and kinematic parameters associated with derivatives of the thermodynamics and wind fields, namely, advection, vorticity, divergence, and deformation, can be obtained by applying Green’s theorem ... -
Clouds and the Earth’s Radiant Energy System (CERES) FluxByCldTyp Edition 4 Data Product
(2022)The Clouds and the Earth’s Radiant Energy System (CERES) project has provided the climate community 20 years of globally observed top of the atmosphere (TOA) fluxes critical for climate and cloud feedback studies. The CERES ... -
A Hybrid Multivariate Deep Learning Network for Multistep Ahead Sea Level Anomaly Forecasting
(2022)The accumulated remote sensing data of altimeters and scatterometers have provided new opportunities for ocean state forecasting and have improved our knowledge of ocean–atmosphere exchanges. Studies on multivariate, ... -
A Fast Mean-Preserving Spline for Interpolating Interval Data
(2022)Interpolation of interval data where the mean is preserved, e.g., estimating smoothed, pseudodaily meteorological variables based on monthly means, is a common problem in the geosciences. Existing methods for mean-preserving ... -
