Use of Underwater Gliders for Acoustic Data Retrieval from Subsurface Oceanographic Instrumentation and Bidirectional Communication in the Deep Ocean
(American Meteorological Society, 2012)any fixed oceanographic instruments and observing systems are deployed in the water column or on the seafloor for extended periods of time without any expression at the sea surface. To routinely communicate with such ... -
Quantifying Dispersal and Connectivity of Surface Waters Using Observational Lagrangian Measurements
(American Meteorological Society, 2012)robability distribution functions of displacement are central to Lagrangian statistics and the study of fluid dispersal. A method for computing marginal probability distributions of passive tracer dispersal from Lagrangian ... -
An Inversion of Acoustical Attenuation Measurements to Deduce Bubble Populations
(American Meteorological Society, 2012)easurement of natural bubble populations is required for many areas of ocean science. Acoustical methods have considerable potential for achieving this goal because bubbles scatter sound strongly close to their natural ... -
An Investigation of the Consistency of TAO–TRITON Buoy-Mounted Capacitance Rain Gauges
(American Meteorological Society, 2012)he common use of remotely located, buoy-mounted capacitance rain gauges in the tropical oceans for satellite rainfall verification studies provides motivation for an in situ gauge bias assessment. A comparison of the biases ... -
Comparison of Two Methods to Assess Ocean Tide Models
(American Meteorological Society, 2012)wo methods to assess ocean tide models, the current method and the total discrepancy method, are compared from the perspective of their relationship to the root-mean-square difference of tidal sea surface height (total ... -
Improving HF Radar Estimates of Surface Currents Using Signal Quality Metrics, with Application to the MVCO High-Resolution Radar System
(American Meteorological Society, 2012)stimates of surface currents over the continental shelf are now regularly made using high-frequency radar (HFR) systems along much of the U.S. coastline. The recently deployed HFR system at the Martha?s Vineyard Coastal ... -
Uncertainty and Intercalibration Analysis of H*Wind
(American Meteorological Society, 2012)he Hurricane Research Division (HRD) Real-time Hurricane Wind Analysis System (H*Wind) is a software application used by NOAA?s HRD to create a gridded tropical cyclone wind analysis based on a wide range of observations. ... -
The Informational Value of Pressure-Based Single-Station Proxies for Storm Activity
(American Meteorological Society, 2012)ir pressure readings and their variations are commonly used to make inferences about storm activity. More precisely, it is assumed that the variation of annual and seasonal statistics of several pressure-based proxies ... -
Study of MPLNET-Derived Aerosol Climatology over Kanpur, India, and Validation of CALIPSO Level 2 Version 3 Backscatter and Extinction Products
(American Meteorological Society, 2012)he level 2 aerosol backscatter and extinction profiles from the NASA Micropulse Lidar Network (MPLNET) at Kanpur, India, have been studied from May 2009 to September 2010. Monthly averaged extinction profiles from MPLNET ... -
Simulating Radar Observations of Precipitation at Higher Frequencies from Lower-Frequency Polarimetric Measurements
