Fast Time Response Tunable Diode Laser Measurements of Atmospheric Trace Gases for Eddy Correlation
(American Meteorological Society, 1988)A fast-response, atmospheric trace gas monitor, based on the principle of tunable diode laser absorption spectroscopy, has been developed for making eddy correlation measurements of dry deposition fluxes. This system, which ... -
A Modulation Waveform for Short-Dwell-Time Meteorogical Doppler Radars
(American Meteorological Society, 1988)A modulation waveform for meteorological Doppler radars that obtain estimates of radar reflectivity, mean velocity, and Doppler width with dwell time much shorter than that used with conventional meteorological Doppler ... -
A C Language-Based Modular System for Analyzing and Displaying Gridded Numerical Data
(American Meteorological Society, 1988)A system for analyzing and displaying gridded numerical data called Candis is described. The system is written in the C programming language, and is built on a standard way of representing such data. The analysis package ... -
The Development of a Fine- and Microstructure Profiler
(American Meteorological Society, 1988)A new freely-falling ocean profiler for measuring finescale variations in temperature, salinity and horizontal velocity and microscale variations in temperature, conductivity, velocity and refractive index has been ... -
Computer Generation of Marine Weather Forecast Text
(American Meteorological Society, 1988)MARWORDS is a natural language text generation system which has been developed to synthesize marine forecasts for the Davis Strait area in Northern Canada. It uses standard manually produced predictions of wind speed, air ... -
On Correcting Radial Orbit Errors for Altimetric Satellites Using Crossover Analysis
(American Meteorological Society, 1988)Radial orbit error, defined as the uncertainty in the geocentric altitude of a satellite, is the dominant error in the measurement of sea surface height by a satellite altimeter. Apart from a geographically dependent ... -
Effects of Precipitation on UHF Wind Profiler Measurements
(American Meteorological Society, 1988)Horizontal winds in the presence of precipitation were measured routinely with a UHF (405 MHz) Wind Profiler. The profiler had five beam-pointing positions so independent measurements of horizontal winds could be compared ... -
Determination of Winds from Balloon Tracking with a Doppler Weather Radar
(American Meteorological Society, 1988)Computer programs for antenna control and data processing were prepared and interfacing was fabricated to enable the Doppler radar at Norman, Oklahoma, to track a reflectorized balloon, and define winds in the layer through ... -
A UHF Wind Profiler for the Boundary Layer: Brief Description and Initial Results
(American Meteorological Society, 1988)In this paper we describe a boundary layer radar recently developed at NOAA's Aeronomy Laboratory. This radar extends wind profiler technology by using a small, relatively inexpensive radar to provide continuous, high-resolution ... -
Modification of a Commercial Gas Filter Correlation CO Detector for Enhanced Sensitivity
(American Meteorological Society, 1988)Carbon monoxide is important in tropospheric chemsitry and useful in studies of cloud dynamics, yet measurements of this gas, especially from aircraft, are too few to characterize fully the atmospheric sources, sinks and ... -
Radar Differential Reflectivity ZDR: A Real-Case Evaluation of Errors Induced by Antenna Characteristics
(American Meteorological Society, 1988)Multiple parameter radar measurements (dual frequency hail signal DFR-HS or differential reflectivity ZDR) can be strongly affected by the mismatch of the antenna illumination functions at the two wavelengths or polarizations. ... -
An Interpretation of Circular Polarization Measurements Affected by Propagation Differential Phase Shift
(American Meteorological Society, 1988)Circularly polarized waves are created by adding horizontally and vertically linearly polarized waves of equal magnitude with a phase difference of 90°. As a transmitted wave propagates through precipitation, which is ... -
Comparison of Sea Surface Wind Measurements Obtained from Buoy, Aircraft and Onshore Masts during the TOSCANE T Campaign
(American Meteorological Society, 1988)The first European Remote Sensing satellite, known as ERS1, will be launched by 1989. Priority in the payload has been given to a comprehensive set of radar instruments designed to observe the surface wind and wave structure ... -

Recalculation of Lightning Localization System Acceptance Using a Refined Damping Model
(American Meteorological Society, 1988)Acceptance of lightning detectors and lightning localization systems has been investigated. Previous calculations based on an exponential damping of the lightning radiation pulse have been repeated using a more sophisticated ... -
TEACHMET: An Expert System for Teaching Weather Forecasting
(American Meteorological Society, 1988)Students or weather forecasting need to learn to identify efficiently the information relevant to the elements they predict. One way students learn these skills is by engaging in discussions of interesting weather situations ... -
On the Accuracy of Monthly Mean Wind Speeds over the Equatorial Pacific
(American Meteorological Society, 1988)Yearlong in situ surface wind measurements at three sites along the Pacific equator (95°, 110°, 152°W) are used to estimate the required number of random observations per month for monthly mean wind speed components accurate ... -
SARDINE: A System for Analyzing, Recording, and Displaying Information from NRL-towchain Experiments
(American Meteorological Society, 1988)In this paper we offer a novel design for shipborne date-acquisition and storage systems?one which combines the technologies of both computers and television. We describe the particular implementation SARDINE, a system ... -
High-Resolution Directional Wave Spectra from Horizontally Mounted Acoustic Doppler Current Meters
(American Meteorological Society, 1988)The paper discusses the estimation of directional wave spectra by the Iterative Maximum Likelihood Method. The performance of the estimate is illustrated using data obtained by an Acoustic Doppler Current Meter in the ...
