Vanes for Sensing Incidence Angles of the Air from an Aircraft
(American Meteorological Society, 1971)Two types of vanes that were used to measure the angle of the airstream with respect to an aircraft are described, analyzed and compared. One type is a rotating vane that is free to align itself with the airstream and the ... -
An Electronic Computing Wind Vane for Turbulence Studies
(American Meteorological Society, 1971)This paper describes an electronic wind vane which has been designed for meteorological support during atmospheric diffusion studies. The wind vane avoids the use of any sliding contacts for giving an analogue record of ... -
A Cloud Simulation Model for Evaluating Automatic Ceilometer Systems
(American Meteorological Society, 1971)A cloud simulation model that is based on a Monte Carlo method was developed for testing and designing automatic ceilometer systems. With this model, cloud plan views and profile views an generated for several different ... -
Applications of an Airborne Ruby Lidar During a BOMEX Program of Cirrus Observations
(American Meteorological Society, 1971)A ruby lidar was mounted in an aircraft to obtain measurements of cirrus and haze layers concurrently with an airborne infrared radiometer during Project BOMEX in July 1969. The capability of the lidar for detecting cirrus ... -
A Narrow-Beam Radiometer for Atmospheric Radiation Studies
(American Meteorological Society, 1971)The design and performance of a narrow-beam radiometer for atmospheric studies are described. It has a beamwidth of 6 mrad and a minimum detectable radiance of 0.0056 mW cm?2 sr?1 in a 1-HZ output bandwidth. The system ... -
Influence of the Atmospheric Aerosol on Albedo
(American Meteorological Society, 1971)The possible climatic effects of the secular increase of aerosols from man's activities have been coupled with the microphysics of the aerosol properties. The magnitude of the critical aerosol absorption coefficient to ... -
Some High Values for the Albedo of the Sea
(American Meteorological Society, 1971)Shipboard shortwave albedo measurements near Bermuda are presented for two widely different sea surface conditions and solar elevations ranging from 25?35°. Good agreement with existing water albedo values was obtained for ... -
The Spectral Reflectance of Natural Surfaces
(American Meteorological Society, 1971)The amount of solar energy reflected from various soils and types of vegetation has been measured as a function of sun elevation in six different wavelength ranges in the ultraviolet, visible and near-infrared regions of ... -
The Responses of Rising or Falling Spherical Wind Sensors to Atmospheric Wind Perturbations
(American Meteorological Society, 1971)The responses of rising or falling spherical wind sensors to atmospheric wind perturbations are analyzed using Fourier transform techniques. The linearized equations of motion of a sensor that is subject to drag and ... -
Two-Point Wind Correlations on an Isobaric Surface in a Nonhomogeneous Non-Isotropic Atmosphere
(American Meteorological Society, 1971)The approximate relations between the correlation coefficient for geopotential, the longitudinal wind component, and the transverse wind component on an isobaric surface in the case of an homogeneous isotropic atmosphere ... -
Sensitivity Calibration of a Dual-Beam Vertically Pointing FM-CW Radar
(American Meteorological Society, 1971)A method of calibrating a fixed vertically pointing radar is presented. The technique involves the firing of B-B shot of known radar cross section through the beam while making successive trajectory corrections until the ... -
X-Band Attenuation and Liquid Water Content Estimation by a Dual-Wavelength Radar
(American Meteorological Society, 1971)Direct measurements of attenuation due to liquid water content (LWC) between two points in the common beam of a dual-wavelength radar system will be possible using a real-time digital processor of radar signals presently ... -
The Use of Broad-Beam Radar for Quantitative Analysis of Severe Storms
(American Meteorological Society, 1971)Methods outlined indicate how an S-band radar with a broad vertical half-power beam width may be used profitably to obtain quantitative data on severe storms. Two Alberta hailstorms were studied using such a radar with ... -
Thunderstorm Water Contents and Rain Fluxes Deduced from Radar
(American Meteorological Society, 1971)Total instantaneous water contents of several intense thunderstorms were calculated from smoothed representations drawn from quantitative radar observations; values typically ranged from 108?109 kg. Rain rates and accumulations ... -
Radar Observations of Land Breeze Fronts
(American Meteorological Society, 1971)In August 1969, the ultra-sensitive 10.7-cm wavelength JAFNA radar at Wallops Island, Va., recorded what was apparently a land breeze front 12?14 n mi off the coast. Accompanying meteorological data show the land breeze ... -
Peak Reading and Thresholding in Processing Radar Weather Data
(American Meteorological Society, 1971)A new PPI map is made up of 600 radial lines, each of 100 dots. Each dot is in one of six shades of grey, thus indicating target intensity, and dot size varies somewhat with shade. Each dot combines k independent data, ... -
An Independent Replication of the Climax Wintertime Orographic Cloud Seeding Experiment
(American Meteorological Society, 1971)An orographic cloud seeding experiment conducted in the vicinity of Climax, Colo., has been continued for five additional wintertime periods from 1965?70. A comparison of this new independent information is made with ...
