Informing Deep Argo Array Design Using Argo and Full-Depth Hydrographic Section Data
(American Meteorological Society, 2015)ata from full-depth closely sampled hydrographic sections and Argo floats are analyzed to inform the design of a future Deep Argo array. Here standard errors of local decadal temperature trends and global decadal trends ... -
Automated Underway Eddy Covariance System for Air–Sea Momentum, Heat, and CO2 Fluxes in the Southern Ocean
(American Meteorological Society, 2016)ruggedized closed-path eddy covariance (EC) system was designed for unattended direct measurements of air?sea momentum, heat, and CO2 flux, and was deployed on the Research Vessel Icebreaker (RV/IB) Nathaniel B. Palmer ... -
Experimental Assessment of the Performance of High-Frequency CODAR and WERA Radars to Measure Ocean Currents in Partially Ice-Covered Waters
(American Meteorological Society, 2016)igh-frequency radars (HFRs) measure ocean surface currents remotely through the Bragg scattering of radio waves by surface gravity waves with wavelengths shorter than 50 m. HFR range is affected by sea ice, which dampens ... -
Assessment of Despiking Methods for Turbulence Data in Micrometeorology
(American Meteorological Society, 2016)he computation of turbulent fluxes of heat, momentum, and greenhouse gases requires measurements taken at high sampling frequencies. An important step in this process involves the detection and removal of sudden, short-lived ... -
Temporal and Spatial Interpolation Errors of High-Resolution Modeled Atmospheric Fields
(American Meteorological Society, 2015)eneral circulation models can now be run at very high spatial resolutions to capture finescale features, but saving the full-spatial-resolution output at every model time step is usually not practical because of storage ... -
An Inductive Charging and Real-Time Communications System for Profiling Moorings
(American Meteorological Society, 2015)his paper describes a system for providing power and communications to moored profiling vehicles. A McLane Moored Profiler (MP) was equipped with a rechargeable battery pack and an inductive charging system to allow it to ... -
Pressure Response of Aanderaa and Sea-Bird Oxygen Optodes
(American Meteorological Society, 2015)his study investigated the effect of hydrostatic pressure of up to 6000 dbar on Aanderaa and Sea-Bird oxygen optodes both in the laboratory and in the field. The overall pressure response is a reduction in the O2 reading ... -
Phase-Resolved Wave Field Simulation Calibration of Sea Surface Reconstruction Using Noncoherent Marine Radar
(American Meteorological Society, 2016)he possibility of reconstructing sea surface wave fields from a noncoherent X-band marine radar return has much potential for maritime operations and ocean engineering. The existing reconstruction method extracts the signal ... -
Comparison of Direct Covariance Flux Measurements from an Offshore Tower and a Buoy
(American Meteorological Society, 2016)irect covariance flux (DCF) measurements taken from floating platforms are contaminated by wave-induced platform motions that need to be removed before computation of the turbulent fluxes. Several correction algorithms ... -
Rainfall-Type Categorization of Radar Echoes Using Polar Coordinate Reflectivity Data
(American Meteorological Society, 2016)n algorithm used to classify precipitation echoes by rain type without interpolating radar data to a constant height is detailed. The method uses reflectivity data without clutter along the lowest available scan angle so ... -
Aerosol Plume Detection Algorithm Based on Image Segmentation of Scanning Atmospheric Lidar Data
(American Meteorological Society, 2016)n image-processing algorithm has been developed to identify aerosol plumes in scanning lidar backscatter data. The images in this case consist of lidar data in a polar coordinate system. Each full lidar scan is taken as a ... -
Principal Component Analysis Approach to Evaluate Instrument Performances in Developing a Cost-Effective Reliable Instrument Network for Atmospheric Measurements
(American Meteorological Society, 2015)eveloping a reliable cost-effective instrument network for data measurement is a challenging task for agency decisionmakers. A simple way to fully characterize the performances of an instrument that also considers economical ... -
Air Oxygen Calibration of Oxygen Optodes on a Profiling Float Array
(American Meteorological Society, 2015)anderaa optode sensors for dissolved oxygen show remarkable stability when deployed on profiling floats, but these sensors suffer from poor calibration because of an apparent drift during storage (storage drift). It has ... -
A Practical Method of Extracting Wind Sea and Swell from Directional Wave Spectrum
(American Meteorological Society, 2015)ind sea and swell representing different weather conditions generally coexist in both open waters and coastal areas, which results in bimodal or multipeaked features in directional wave spectrum. Because they make wave ... -
