In Situ Cloud Sensing with Multiple Scattering Lidar: Simulations and Demonstration
(American Meteorological Society, 2003)Due to the spatially inhomogeneous nature of clouds there are large uncertainties in validating remote sensing retrievals of cloud properties with traditional in situ cloud probes, which have sampling volumes measured in ... -
The Oklahoma Mesonet's Skin Temperature Network
(American Meteorological Society, 2003)In 1999, the Oklahoma Mesonet deployed infrared temperature (IRT) sensors at 89 of its environmental monitoring stations. A 3-yr dataset collected since that time provides a unique opportunity to analyze longer-term, ... -
Performance of Five 915-MHz Wind Profilers and an Associated Automated Quality Control Algorithm in an Operational Environment
(American Meteorological Society, 2003)The accuracy and availability of data from a network of 915-MHz boundary layer wind profilers operated by the U.S. Air Force on the Eastern Range are assessed using an automated quality control (QC) algorithm developed by ... -
An Assessment of Aircraft-Generated Contamination on In Situ Trace Gas Measurements: Determinations from Empirical Data Acquired Aloft
(American Meteorological Society, 2003)Results are reported from an experiment conducted aboard the NASA DC-8 research aircraft to determine whether cabin air vented upstream of investigator's inlets had potentially contaminated ambient air samples obtained ... -
Dynamic Response of the Fine Wire Psychrometer for Direct Measurement of Water Vapor Flux
(American Meteorological Society, 1986)For the measurement of humidity fluctuation in the atmospheric boundary layer, a wet- and dry-bulb ther-mocouple psychrometer has been used traditionally. However, in the direct measurement of water vapor flux with the ... -
Rain Gauge and Disdrometer Measurements during the Keys Area Microphysics Project (KAMP)
(American Meteorological Society, 2003)Four impact disdrometers and 27 tipping bucket rain gauges were operated at 11 different sites during August and September 2001, as part of the Keys Area Microphysics Project. The rain gauge and disdrometer network was ... -
Whitening in Range to Improve Weather Radar Spectral Moment Estimates. Part II: Experimental Evaluation
(American Meteorological Society, 2003)Demonstration of a method for improved Doppler spectral moment estimation is made on NOAA's research and development Weather Surveillance Radar-1988 Doppler (WSR-88D) in Norman, Oklahoma. Time series data have been recorded ... -
Whitening in Range to Improve Weather Radar Spectral Moment Estimates. Part I: Formulation and Simulation
(American Meteorological Society, 2003)A method for estimation of spectral moments on pulsed weather radars is presented. This scheme operates on oversampled echoes in range; that is, samples of in-phase and quadrature-phase components are collected at a rate ... -
Near-Real-Time Measurement of Sea-Salt Aerosol during the SEAS Campaign: Comparison of Emission-Based Sodium Detection with an Aerosol Volatility Technique
(American Meteorological Society, 2003)The first deployment of an emission-based aerosol sodium detector (ASD), designed to chemically characterize marine aerosols on a near-real-time basis, is reported. Deployment occurred as part of the Shoreline Environment ... -
The Use of Direct Observations over the Aerosol Particle Size Distribution for Inverting Lidar Data
(American Meteorological Society, 2003)The work is concerned with the inversion of horizontal lidar data into the aerosol particle size distribution (APSD). The aerosol is assumed to consist of spherical particles of continental and oceanic origin. The particular ... -
Aerosol Size Distributions from Genetic Inversion of Polar Nephelometer Data
(American Meteorological Society, 2003)It is shown that genetic inversions can be used to recover lognormal aerosol size distributions from multiangle optical scattering cross-section data measured by a polar nephelometer at a wavelength of 0.532 ?m. The ... -
A Study of the Extinction-to-Backscatter Ratio of Marine Aerosol during the Shoreline Environment Aerosol Study
(American Meteorological Society, 2003)Ground-based aerosol optical measurements made at near-ambient relative humidity (RH) under clean marine sampling conditions are presented and compared to 1) almost identical optical measurements made at a polluted continental ... -
Vertical and Horizontal Aerosol Scattering Fields over Bellows Beach, Oahu, during the SEAS Experiment
(American Meteorological Society, 2003)Scanning lidar measurements were carried out during the Shoreline Environment Aerosol Study (SEAS) experiment (19?30 April 2000) to characterize the aerosol scattering fields in the coastal marine boundary layer at Bellows ... -
Sea-Salt Size Distributions from Breaking Waves: Implications for Marine Aerosol Production and Optical Extinction Measurements during SEAS
(American Meteorological Society, 2003)The authors' participation in the Shoreline Environment Aerosol Study (SEAS) involved measurements focused on the coastal aerosol size distribution and related optical measurements, including aerosol light scattering, ... -
The Shoreline Environment Aerosol Study (SEAS): A Context for Marine Aerosol Measurements Influenced by a Coastal Environment and Long-Range Transport
(American Meteorological Society, 2003)The Shoreline Environment Aerosol Study (SEAS) was carried out in Hawaii on the southeast coast of Oahu in an area exposed to relatively steady onshore flow. This location provided favorable opportunities to test and ... -
Comparison of Eddy Dissipation Rates from Spatial Spectra of Doppler Velocities and Doppler Spectrum Widths
(American Meteorological Society, 1986)Doppler radars offer unique data from which it is possible to estimate the turbulent eddy dissipation rates, ?. If the inertial subrange extends to lengths longer than the radar resolution volume size, ? can be obtained ... -

The RADARSAT Geophysical Processor System: Quality of Sea Ice Trajectory and Deformation Estimates
(American Meteorological Society, 2003)NASA's RADARSAT Geophysical Processor System (RGPS) uses sequential synthetic aperture radar (SAR) images to track the trajectories of some 30 000 points on the Arctic sea ice for periods of up to 6 months. Much of the ... -
Optical Measurement of Bubbles: System Design and Application
(American Meteorological Society, 2003)Affordable high quality charge-coupled device (CCD) video cameras and image processing software are powerful tools for bubble measurements. Because of the wide variation between bubble populations, different bubble measurement ... -
