A Miniature Acoustic Device for Tracking Small Marine Animals or Submerged Drifters
(American Meteorological Society, 2017)AbstractThis paper presents an acoustic archival tag capable of tracking small marine animals. It is also a technology that can be ported to other platforms, such as the next-generation acoustic and Argo floats as well as ... -
Statistical Analysis of the Quantified Relationship between Evaporation Duct and Oceanic Evaporation for Unstable Conditions
(American Meteorological Society, 2017)AbstractAn analysis is conducted for the first time to statistically quantify the relationship between the evaporation duct and oceanic evaporation. Through sensitivity analysis, under unstable conditions (air?sea temperature ... -
The Oklahoma Meso-Scale Integrated Socio-Geographic Network: A Technical Overview
(American Meteorological Society, 2017)AbstractEstablished as a social companion to the Oklahoma Mesonet, the Oklahoma Meso-Scale Integrated Socio-Geographic Network (M-SISNet) is a network of approximately 1500 ?social monitoring stations? (geolocated households) ... -
A Simple Nonlinear and End-Member-Free Approach for Obtaining Ocean Remineralization Patterns
(American Meteorological Society, 2017)AbstractThe variability of a biogeochemical property in the ocean is the outcome of both nonconservative (such as respiration and photosynthesis) and conservative (mixing of water masses with distinct concentrations at ... -
A Noninterpolated Estimate of Horizontal Spatial Covariance from Nonorthogonally and Irregularly Sampled Scalar Velocities
(American Meteorological Society, 2017)AbstractThis paper presents a least squares method to estimate the horizontal (isotropic or anisotropic) spatial covariance of two-dimensional orthogonal vector components, without introducing an intervening mapping step ... -
Untitled
(American Meteorological Society, 2017)AbstractOpen-path eddy covariance systems are widely used for measuring the CO2 flux between land and atmosphere. A common problem is that they often yield negative fluxes or physiologically unreasonable CO2 uptake fluxes ... -
Observations of Convective Thermals with Weather Radar
(American Meteorological Society, 2017)AbstractIt is shown that the NEXRAD weather radar with enhanced detectability is capable of observing the evolution of convective thermals. The fields of radar differential reflectivity show that the upper parts of the ... -
Evaluation of Satellite and Reanalysis Wind Products with In Situ Wave Glider Wind Observations in the Southern Ocean
(American Meteorological Society, 2017)AbstractSurface ocean wind datasets are required to be of high spatial and temporal resolution and high precision to accurately force or be assimilated into coupled atmosphere?ocean numerical models and to understand ... -
A Comparison of Vertical Atmospheric Wind Profiles Obtained from Monostatic Sodar and Unmanned Aerial Vehicle–Based Acoustic Tomography
(American Meteorological Society, 2017)AbstractThe natural sound generated by an unmanned aerial vehicle is used in conjunction with tomography to remotely sense the virtual temperature and wind profiles of the atmosphere in a horizontal plane up to an altitude ... -
A New Technique to Estimate Sensible Heat Fluxes around Micrometeorological Towers Using Small Unmanned Aircraft Systems
(American Meteorological Society, 2017)AbstractUpscaling point measurements from micrometeorological towers is a challenging task that is important for a variety of applications, for example, in process studies of convection initiation, carbon and energy budget ... -
Response to Temperature of a Class of In Situ Hyperspectral Radiometers
(American Meteorological Society, 2017)AbstractThe response to temperature of sample hyperspectral radiometers commonly used to support the validation of satellite ocean color data was characterized in the 400?800-nm spectral range. Measurements performed in ... -
Shallow Precipitation Detection and Classification Using Multifrequency Radar Observations and Model Simulations
(American Meteorological Society, 2017)AbstractDetection of shallow warm rainfall remains a critical source of uncertainty in remote sensing of precipitation, especially in regions of complex topographic and radiometric transitions, such as mountains and ... -
Testing a Novel Method for Initializing Air Parcel Back Trajectories in Precipitating Clouds Using Reanalysis Data
(American Meteorological Society, 2017)AbstractLagrangian air parcel tracking is a powerful tool for estimating vapor source locations, particularly for isotope hydrology applications. Identified vapor source regions may be sensitive to the distribution of ... -
On Determining Stationary Periods within Time Series
(American Meteorological Society, 2017)AbstractA novel approach is constructed for determining both the occurrence and the duration of stationary periods within time series. After reviewing four statistical techniques that provide stationarity measures invariant ... -
Coupling of Wave Data and Underwater Acoustic Measurements in a Maritime High-Traffic Coastal Area: A Case Study in the Strait of Sicily
(American Meteorological Society, 2017)AbstractUnderwater acoustic monitoring combined with real-time sea surface observations and numerical model forecasts could improve the efficiency of natural and anthropogenic sound source discrimination. In this work, ... -
Evaluation of Optical Proxies for Suspended Particulate Mass in Stratified Waters
(American Meteorological Society, 2017)AbstractOptical instruments that measure the particulate beam attenuation and backscattering coefficients have been used widely to estimate suspended particulate mass (SPM) in various environments. In pycnoclines, density ... -
