Lidar Sensing of Plume Dispersion: Analysis Methods and Product Quality for Light-Scattering Tracer Particles
(American Meteorological Society, 1987)Analysis procedures are described for retrieving accurate plume information from lidar data on light-scattering particles during atmospheric dispersion experiments. Interactive computer graphics aided in the solution of ... -
Influence of Sensor Configuration on Measurements of Dry and Wet Bulb Temperature Fluctuations
(American Meteorological Society, 1987)Measurements of dry and wet bulb temperature fluctuations in the atmospheric boundary layer are often accomplished with sensors consisting of a relatively long resistance wire mounted on some kind of supporting frame. It ... -
Intercomparison of Cloud Imagery from the DMSP OLS, NOAA AVHRR, GOES VISSR, and Landsat MSS
(American Meteorological Society, 1987)Concurrent visible and infrared imagery from four satellite sensors (DMSP OLS, NOAA AVHRR, GOES VISSR, Landsat MSS) have been intercompared. Inherent differences in observed cloud properties and cloud field analyses are ... -
Relations Among Linear and Circulur Polarization Parameters Measured in Canted Hydrometeors
(American Meteorological Society, 1987)Parameters derived from measurements using circular and linear polarizations are mathematically interrelated. In this work this interdependence is investigated. It is shown that circular and linear polarization parameters ... -
The Measurement of Doppler Wind Fields with Fast Scanning Radars: Signal Processing Techniques
(American Meteorological Society, 1987)This paper discusses signal processing techniques being developed for making Doppler wind velocity measurements using airport surveillance radars. Techniques are presented and evaluated for velocity estimation using ... -
The Influence of Sampling and Filtering on Measured Wind Gusts
(American Meteorological Society, 1987)The theory by Rice for extreme value statistics is used to study the influence of filters in a wind measuring system on the measured gusts. An extension is made to discretely sampled data. Model results are compared with ... -
Applications of Fast Response Continuous SF6 Analyzers to In Situ Cloud Studies
(American Meteorological Society, 1987)The airborne applications of two recently developed analyzers for sulfur hexafluoride (SF6) to investigations of cloud top mixing and cloud seeding are described. The analyzers were developed by AeroVironment (AV) and by ... -
Rain Rate Estimates from Differential Polarization Measurements
(American Meteorological Society, 1987)This paper presents an analysis of the accuracy of rain rate estimates from data observed with a radar that has alternating horizontal and vertical polarization. Theoretical accuracies of rain rates from the reflectivity, ... -
A Velocity Measurement Technique for Tornado Vortex Simulators
(American Meteorological Society, 1987)A technique utilizing stereo-photogrammetry of neutrally buoyant bubbles in a tornado vortex chamber (TVC) is described. This technique is advantageous over others inasmuch as it is nonintrusive and does not require the ... -
Real-Time Screening Techniques for Doppler Current Profiler Data
(American Meteorological Society, 1987)Computationally simple criteria for the identification of spurious Doppler profiler velocity estimates are described and evaluated. Their effectiveness is determined by changes in the confidence intervals and mean values ... -
The Precision and Relative Accuracy of Profiler Wind Measurements
(American Meteorological Society, 1987)Two independent wind profiles were measured every hour during February 1986 with a five-beam, UHF (405 MHz) wind Profiler at Platteville, Colorado. Our analysis of the horizontal wind components over all heights for the ... -
Calibration of METEOSAT Infrared Radiometer using Split Window Channels of NOAA AVHRR
(American Meteorological Society, 1987)A multispectral/multiangular procedure is proposed to calibrate the infrared channel of METEOSAT-2 IR 1 (760?980 cm?1), using the radiances of NOAA-7 AVHRR channels 4 (870?980 cm?1) and 5 (795?885 cm?1). The METEOSAT ... -
Corrigendum
(American Meteorological Society, 1987)Correction to Volume 4, Issue 2, pages 348-350. -
Improved Depth and Temperature Conversion Equations for Sippican AXBTs
(American Meteorological Society, 1987)In October 1985, in a region of large-scale thermohaline ?staircases? off the northeast coast of South America, five shallow and seven deep Sippican AXBTs (air deployed expendable bathythermographs) were hand deployed from ... -

A Microcomputer Data-Acquisition System for Real-Time Processing of Raindrop Size Distribution Measured with the RD69 Distrometer
(American Meteorological Society, 1987)The disdrometer is an instrument used worldwide to measure the size distribution of raindrops at ground level. In this paper, a data-acquisition and real-time processing system designed for disdrometer measurements is ... -
Sea Surface Currents in the Equatorial Pacific from VHF Radar Backscatter Observations
(American Meteorological Society, 1987)We present the analysis of three months of continuous sea-surface current data obtained by a VHF wind profiling radar at Christmas Island in the central equatorial Pacific. These results, which were obtained during the ... -

The Effect of Calibration of the Forward-Scattering Spectrometer Probe on the Sizing of Cloud Droplets
(American Meteorological Society, 1987)Cloud droplets were measured from an aircraft with an FSSP in summer cloud and in winter cloud. For 70 cloud penetrations, three cloud droplet volume spectra were derived using three different calibration schemes. The ... -
Attenuation of a 5-cm Wavelength Radar Signal in the Lahoma-Orienta Storms
(American Meteorological Society, 1987)Attenuation problems arise when short wavelength radar is used for severe storm identification and structure analysis. These are illustrated by comparing observations from 5- and 10-cm Doppler radars. Reduced and fragmented ...
