Calibration Results for NOAA-11 AVHRR Channels 1 and 2 from Congruent Path Aircraft Observations
(American Meteorological Society, 1993)A method for using congruent atmospheric path aircraft-satellite observations to calibrate a satellite radiometer is presented. A calibrated spectroradiometer aboard a NASA ER-2 aircraft at an altitude of 19 km above White ... -
A High-Power, Dual-Frequency Monostatic Acoustic Sounder for Studying the Atmospheric Boundary Layer
(American Meteorological Society, 1993)Microwave propagation conditions in the lower marine troposphere are evaluated using gradients of radio refractivity profiles. An inexpensive, weather-resistant system for Continuous monitoring of radio refractivity ... -
Estimating the Path-Average Rainwater Content and Updraft Speed along a Microwave Link
(American Meteorological Society, 1993)While there are many microwave techniques proposed for measuring the rate of rainfall in still air (Ro) there is a scarcity of methods for accurately estimating the mass of rainwater rather than its flux. A recently proposed ... -
Separation of Propagation and Backscattering Effects in Rain for Circular Polarization Diversity S-Band Radars
(American Meteorological Society, 1993)Because precipitation particles are generally nonspherical, not only will microwave radiation be depolarized when reflected by precipitation, but also the polarization state of the transmitted wave will change as the radar ... -
A Deep-Sea Differential Pressure Gauge
(American Meteorological Society, 1984)A pressure gauge configured to respond to the difference between the ocean pressure and the pressure within a confined volume of compressible oil is found to be especially useful for detecting pressure fluctuations in the ... -
Quality Controls for Profiler Measurements of Winds and RASS Temperatures
(American Meteorological Society, 1993)A new method for estimating winds and radio acoustic sounding system temperatures from radar Doppler measurements for the new NOAA wind profilers is described. This method emphasizes the quality of 6-min measurements prior ... -
Tracking Hurricane Claudette with the U.S. Air Force Over-the-Horizon Radar
(American Meteorological Society, 1993)Hurricane Claudette was successfully tracked for three days using the 2-s (7 m) surface wave direction field mapped by the U.S. Air Force OTH-B over-the-horizon radar 2400 km away on the coast of Maine. Inflow and fine ... -

Comments on “VHF Radar Measurements of In-Beam Incidence Angles and Associated Vertical-Beam Radial Velocity Corrections”
(American Meteorological Society, 1993)No abstract available -
Auxiliary Signal Processing System for a Multiparameter Radar
(American Meteorological Society, 1993)The design of an auxiliary signal processor for a multiparameter radar is described with emphasis on low cost, quick development, and minimum disruption of radar operations. The processor is based around a low-cost digital ... -
Field Performance of a Spinning-Reflector Microwave Radiometer
(American Meteorological Society, 1993)In the winter of 1986, two microwave radiometers were operated side by side at a high-altitude weather observation site in the central Sierra Nevada for the purpose of comparing measurements in a variety of ambient weather ... -
Constraints on the Repetitivity of the Orbit of an Altimetric Satellite: Estimation of the Cross-Track Slope
(American Meteorological Society, 1993)The effect of a poorly constrained repetitivity of the orbit of an altimetric satellite is analyzed. From existing data, 35% of the marine geoid slopes are found to excess 1.5 cm km?1. This may be due either to ... -
Comparison of Different Bin-mapping Methods for a Bottom-mounted Acoustic Profiler
(American Meteorological Society, 1993)Acouste Doppler current profilers (ADCPS) can measure profiles of velocity components and some other properties of bodies of water. If the profiler is firmly mounted, the profiles can be recorded without immediate coordinate ... -
An Efficient Sound Source for Wide-Area RAFOS Navigation
(American Meteorological Society, 1993)To meet the expected need for wide-area acoustic navigation for Lagrangian studies of ocean circulation using RAFOS floats, a new and powerful sound source, a resonant pipe projector has been developed. It consists of a ... -
A Vertical Coordinate Mapping Technique for Semispectral Primitive Equation Models of Oceanic Circulation
(American Meteorological Society, 1993)A stretched coordinate technique for semispectral hydrodynamic models is described that allows for greater flexibility in the placement of model grid points. Stretching is implemented here for the vertical coordinate of ... -
TOPS: A Free-Fall Velocity and CTD Profiler
(American Meteorological Society, 1984)A free-fall instrument, TOPS, measures vertical profiles of horizontal ocean velocity, conductivity and temperature. Profiling capability extends throughout the full water column (6000 db pressure limitation). Larger ... -
Direct Calculation of Low-Frequency Coastally Trapped Waves and Their Scattering
(American Meteorological Society, 1993)A new, direct numerical method is proposed for finding the phase speeds and pressure fields of low-frequency nondispersive coastally trapped waves in a continuously stratified flow. The usual two-dimensional problem is ... -
A Proposed Definition for Vector Correlation in Geophysics: Theory and Application
(American Meteorological Society, 1993)A universally accepted definition for vector correlation in oceanography and meteorology does not presently exist. To address this need, a generalized correlation coefficient, originally proposed by Hooper and later expanded ... -
Measurement of Temperature Spectra by a Sonic Anemometer
(American Meteorological Society, 1993)The response of a Kaijo Denki DAT 300 ultrasonic anemometer-thermometer is analyzed with respect to temperature and vertical velocity. The effects of the emitting-receiving cycle of the transducer array on w, T, and CowT ... -
Development and Characterization of a New Solar Ultraviolet-B Irradiance Detector
(American Meteorological Society, 1993)Characteristics of an instrument for measuring solar ultraviolet-B irradiance are presented together with a description of the instrument. The instrument measures direct and scattered broadband ultraviolet irradiance ...
