The Generation and Detection of Sound Emitted by Aircraft Wake Vortices in Ground Effect
(American Meteorological Society, 2005)Sound recorded by the author in March 2002 at JFK International Airport shows that wake vortices in ground effect emit infrasound that is 1) more than 40 dB stronger than audible wake vortex sound; 2) substantially stronger ... -
Effects of a Spectral Surface Reflectance on Measurements of Backscattered Solar Radiation: Application to the MOPITT Methane Retrieval
(American Meteorological Society, 2005)The amount of solar radiation emerging from the top of the atmosphere is strongly influenced by the reflectance of the underlying surface. For this reason, some information about the magnitude and the spectral variability ... -
Test of a Staggered PRT Scheme for the French Radar Network
(American Meteorological Society, 2005)This paper describes the test of a staggered PRT scheme for the French radar network. The design of the staggered scheme has been done in the following context: 1) the scheme is meant to be implemented on existing C-band ... -
Measurement of Low Amounts of Precipitable Water Vapor Using Ground-Based Millimeterwave Radiometry
(American Meteorological Society, 2005)Extremely dry conditions characterized by amounts of precipitable water vapor (PWV) as low as 1?2 mm commonly occur in high-latitude regions during the winter months. While such dry atmospheres carry only a few percent of ... -
Assessment of Cirrus Cloud Optical and Microphysical Data Reliability by Applying Statistical Procedures
(American Meteorological Society, 2005)A methodology of employing statistical procedures, specifically the principal component analysis (PCA) technique, to assess cirrus cloud data reliability is described. The approach is demonstrated by an example of a study ... -
On the USCRN Temperature System
(American Meteorological Society, 2005)In 2004 a new aspirated surface air temperature system was officially deployed nationally in the U.S. Climate Reference Network (USCRN) commissioned by the National Oceanic and Atmospheric Administration. The primary goal ... -
Temporal Sampling: How Many Sections Are Needed to Quantify the Mean Transport and Structure of a Meandering Current?
(American Meteorological Society, 2005)Two years of observations from an array of 16 inverted echo sounders deployed south of Australia near 51°S, 143.5°E are combined with hydrographic observations from the region to estimate the differences in baroclinic ... -
Intersatellite Radiance Biases for the High-Resolution Infrared Radiation Sounders (HIRS) on board NOAA-15, -16, and -17 from Simultaneous Nadir Observations
(American Meteorological Society, 2005)Intersatellite radiance comparisons for the 19 infrared channels of the High-Resolution Infrared Radiation Sounders (HIRS) on board NOAA-15, -16, and -17 are performed with simultaneous nadir observations at the orbital ... -
Angular Distribution Models for Top-of-Atmosphere Radiative Flux Estimation from the Clouds and the Earth’s Radiant Energy System Instrument on the Terra Satellite. Part I: Methodology
(American Meteorological Society, 2005)The Clouds and Earth?s Radiant Energy System (CERES) provides coincident global cloud and aerosol properties together with reflected solar, emitted terrestrial longwave, and infrared window radiative fluxes. These data are ... -
Observations of Steep Wave Statistics in Open Ocean Waters
(American Meteorological Society, 2005)A new wavelet analysis methodology is proposed to estimate the statistics of steep waves. The method is applied to open ocean wave height data from the Southern Ocean Waves Experiment (1992) and from a field experiment ... -
Directionality and Crest Length Statistics of Steep Waves in Open Ocean Waters
(American Meteorological Society, 2005)A new wavelet analysis methodology is applied to open ocean wave height data from the Southern Ocean Waves Experiment (1992) and from a field experiment conducted at Duck, North Carolina, in 1997 with the aim of estimating ... -
Remote Sensing of Atmospheric Water Vapor Using the Moderate Resolution Imaging Spectroradiometer
(American Meteorological Society, 2005)This paper presents first validation results for an algorithm developed for the retrieval of integrated columnar water vapor from measurements of the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on board ... -
High-Frequency Single-Board Doppler Minisodar for Precipitation Measurements. Part I: Rainfall and Hail
(American Meteorological Society, 2005)A high-frequency Doppler sodar for precipitation measurements has been developed. Such a Doppler sodar (6?20 kHz) can almost always measure precipitation and turbulence spectra simultaneously. Therefore, the mean vertical ... -
A New Nonparametric Method to Correct Model Data: Application to Significant Wave Height from the ERA-40 Re-Analysis
(American Meteorological Society, 2005)A new nonparametric method to correct model data is proposed. At any given point in space and time the correction is determined from ?analogs? in a learning dataset. The learning dataset contains model data and simultaneous ... -
Drift Characteristics of a Moored Conductivity–Temperature–Depth Sensor and Correction of Salinity Data
