Microstructure Measurements from an Underwater Glider in the Turbulent Faroe Bank Channel Overflow
(American Meteorological Society, 2014)easurements of ocean microstructure are made in the turbulent Faroe Bank Channel overflow using a turbulence instrument attached to an underwater glider. Dissipation rate of turbulent kinetic energy ε is measured using ... -
On “Gridless” Interpolation and Subgrid Data Density
(American Meteorological Society, 2014)earest-neighbor gridding, binning, and bin-averaging procedures are performed routinely to map the irregularly sampled data onto a grid for data analysis and assimilation. Because these procedures are actually an interpolation ... -
Utility-Scale Wind Turbine Wake Characterization Using Nacelle-Based Long-Range Scanning Lidar
(American Meteorological Society, 2014)o facilitate the optimization of turbine spacing at modern wind farms, computational simulations of wake effects must be validated through comparison with full-scale field measurements of wakes from utility-scale turbines ... -
Stereophotogrammetry of Oceanic Clouds
(American Meteorological Society, 2014)his study extends ground-based stereophotogrammetry of clouds to oceanic settings, where there are often none of the landmarks used in traditional camera calibration. This paper introduces a zero-landmark calibration ... -
High-Resolution Raindrop Size Distribution Retrieval Based on the Doppler Spectrum in the Case of Slant Profiling Radar
(American Meteorological Society, 2015)oppler spectra from vertically profiling radars are usually considered to retrieve the raindrop size distribution (DSD). However, to exploit both fall velocity spectrum and polarimetric measurements, Doppler spectra acquired ... -
Determining Functional Relations in Multivariate Oceanographic Systems: Model II Multiple Linear Regression
(American Meteorological Society, 2014)method for estimating multivariate functional relationships between sets of measured oceanographic, meteorological, and other field data is presented. Model II regression is well known for describing functional relationships ... -
A Low-Cost Wireless Temperature Sensor: Evaluation for Use in Environmental Monitoring Applications
(American Meteorological Society, 2014)wide range of environmental applications would benefit from a dense network of air temperature observations. However, with limitations of costs, existing siting guidelines, and risk of damage, new methods are required to ... -
Adaptive Range Oversampling to Improve Estimates of Polarimetric Variables on Weather Radars
(American Meteorological Society, 2014)ne way to reduce the variance of meteorological-variable estimates on weather radars without increasing dwell times is by using range oversampling techniques. Such techniques could significantly improve the estimation of ... -
Correction of UVS-AB-T UV Radiometers Using a Radiative Transfer Model
(American Meteorological Society, 2014)bservation of UV radiation is of major importance to human health and to the calculation of photochemical reaction rates. However, the sensitivity of UV radiometers decays because of equipment aging. A correction method ... -
Sea State Determination from Ship-Based Geodetic GPS
(American Meteorological Society, 2014)cean waves have a profound impact on navigation, offshore operations, recreation, safety, and the economic vitality of a nation?s maritime and coastal communities. This study demonstrates that ships equipped with geodetic ... -
Cooperation or Coordination of Underwater Glider Networks? An Assessment from Observing System Simulation Experiments in the Ligurian Sea
(American Meteorological Society, 2014)he coordinated and cooperative-unaware networking of glider fleets have been proposed to obtain a performance gain in ocean sampling over naïve collective behavior. Whether one of these implementations results in a more ... -
