An Evaluation of Radiometric Products from Fixed-Depth and Continuous In-Water Profile Data from Moderately Complex Waters
(American Meteorological Society, 2009)Radiometric products determined from fixed-depth and continuous in-water profile data collected at a coastal site characterized by moderately complex waters were compared to investigate differences and limitations between ... -
Mixing Measurements on an Equatorial Ocean Mooring
(American Meteorological Society, 2009)Vaned, internally recording instruments that measure temperature fluctuations using FP07 thermistors, including fluctuations in the turbulence wavenumber band, have been built, tested, and deployed on a Tropical Atmosphere ... -
Thermal Mass Correction for the Evaluation of Salinity
(American Meteorological Society, 2009)This paper revisits the thermal mass inertia correction of Sea-Bird Electronics, Inc., (SBE4) conductivity probes for the calculation of salinity. In particular, it is shown that the standard parameters recommended for the ... -
In Situ Data Biases and Recent Ocean Heat Content Variability
(American Meteorological Society, 2009)Two significant instrument biases have been identified in the in situ profile data used to estimate globally integrated upper-ocean heat content. A large cold bias was discovered in a small fraction of Argo floats along ... -
A New Apparatus for Monitoring Sea Ice Thickness Based on the Magnetostrictive-Delay-Line Principle
(American Meteorological Society, 2009)High-precision ice thickness observations are required to gain a better understanding of ocean?ice?atmosphere interactions and to validate numerical sea ice models. A new apparatus for monitoring sea ice and snow thickness ... -
Spectral Partitioning and Identification of Wind Sea and Swell
(American Meteorological Society, 2009)In this paper, different partitioning techniques and methods to identify wind sea and swell are investigated, addressing both 1D and 2D schemes. Current partitioning techniques depend largely on arbitrary parameterizations ... -
The Temporal Aliasing Formulas for the Tandem Mission of Jason-1 and TOPEX/Poseidon
(American Meteorological Society, 2009)The temporal aliasing formulas are derived for the Tandem Mission of Jason-1 and the Ocean Topography Experiment (TOPEX)/Poseidon. Previously, aliasing formulas were derived for a single satellite or a constellation of ... -
Improved Turbulent Air–Sea Flux Bulk Parameters for Controlling the Response of the Ocean Mixed Layer: A Sequential Data Assimilation Approach
(American Meteorological Society, 2009)Bulk formulations parameterizing turbulent air?sea fluxes remain among the main sources of error in present-day ocean models. The objective of this study is to investigate the possibility of estimating the turbulent bulk ... -
Improved ENSO Prediction by Singular Vector Analysis in a Hybrid Coupled Model
(American Meteorological Society, 2009)In this study, a method based on singular vector analysis is proposed to improve El Niño?Southern Oscillation (ENSO) predictions. Its essential idea is that the initial errors are projected onto their optimal growth patterns, ... -
Analysis of Short Space–Time-Scale Variability of Oceanic Rain Using TOPEX/Jason
(American Meteorological Society, 2009)Information on the spatial and temporal variability of rain rate is important not only for meteorology and hydrology but also for the design of remote sensing and in situ measuring or of millimeter wave communication ... -
Stray Light Correction of the Marine Optical System
(American Meteorological Society, 2009)The Marine Optical System is a spectrograph-based sensor used on the Marine Optical Buoy for the vicarious calibration of ocean color satellite sensors. It is also deployed from ships in instruments used to develop bio-optical ... -
Validation of Jason-1 and Envisat Remotely Sensed Wave Heights
(American Meteorological Society, 2009)Satellite altimetry provides an immensely valuable source of operational significant wave height (Hs) data. Currently, altimeters on board Jason-1 and Envisat provide global Hs observations, available within 3?5 h of real ... -
Automated Ice-Tethered Profilers for Seawater Observations under Pack Ice in All Seasons
(American Meteorological Society, 2008)An automated, easily deployed Ice-Tethered Profiler (ITP) instrument system, developed for deployment on perennial sea ice in the polar oceans to measure changes in upper ocean water properties in all seasons, is described, ... -
A Three-Dimensional Variational Data Assimilation Scheme for the Regional Ocean Modeling System
(American Meteorological Society, 2008)A three-dimensional variational data assimilation (3DVAR) scheme has been developed within the framework of the Regional Ocean Modeling System (ROMS). This ROMS3DVAR enables the capability of predicting meso- to small-scale ... -
Modeling Pulse-to-Pulse Coherent Doppler Sonar
(American Meteorological Society, 2008)Coherent Doppler sonar provides a powerful tool for probing boundary layer flows under field and laboratory conditions. However, velocity profiling applications of this technique are complicated by characteristic velocity ... -
De-Aliasing of Large-Scale High-Frequency Barotropic Signals from Satellite Altimetry in the Japan/East Sea
(American Meteorological Society, 2008)In the Japan/East Sea, energetic high-frequency large-scale barotropic motions are shown to lead to large aliasing errors in satellite altimetry observations. The combined aliasing from several neighboring and crossing ... -
