Analysis of Ground Tests of a Microwave, Earth-Occultation, Pressure-Reference-Level System
(American Meteorological Society, 1973)Satellite infrared sounding instruments, such as SIRS and VTPR, generate temperature profiles as a function of pressure. A two-satellite, microwave, earth-occultation system can supplement an infrared sensor by providing ... -
Stratospheric Temperature Profiles from Limb Radiance Measurements
(American Meteorological Society, 1973)Stlratospheric temperature profiles have been inferred from limb radiance data. The limb radiance observations were made from an Aerobee rocket flown on 7 February 1970 from White Sands Missile Range, N.M. The inferred ... -
Low Density Extremes for Ground Elevations up to 15,000 ft
(American Meteorological Society, 1973)Atmospheric density, especially low values thereof, is important to aircraft takeoff and landing operations; therefore, probable extremes of low density are needed for aircraft design. This document provides for the most ... -
A Study of Hailswaths by Means of Airborne Infrared Radiometry
(American Meteorological Society, 1973)Further results on the airborne mapping of hailswaths with both fixed beam and scanning IR radiometers are described. It was ascertained that the scanning radiometer made a valuable contribution toward the determination ... -
A Dual-Wavelength Radar Hail Detector
(American Meteorological Society, 1973)It is proposed that the range derivative of the logarithm of the ratio of average echo powers from two (S- and X-band) synchronized and slaved radars would yield a highly reliable indication of the boundaries of hail shafts. ... -
A Measurement of the Velocity Field of a Cumulus Cloud
(American Meteorological Society, 1973)A 3-hr flight of a constant-volume balloon which is entrained into a cumulus congestus cloud and lifted to an altitude of nearly 3 km provides an opportunity to determine the trajectory and vertical velocity of the balloon ... -
Experiments on Collection Efficiency. I. The Collection of a Vented Aerodynamic Probe
(American Meteorological Society, 1973)This paper shows the necessity of determining experimentally the collection efficiency of an aerodynamic probe, before using it to collect an aerosol. The experimental techniques described herein, although applied to a ... -
A Cloud Nucleus Counter with Long Available Growth Time
(American Meteorological Society, 1973)A vertical plate, steady-flow, thermal diffusion chamber designed for use as a cloud condensation nucleus counter is described. In this instrument, phoretic forces are shown to limit the maximum available growth time to a ... -
The Size Distribution and Inland Penetration of Sea-Salt Particles
(American Meteorological Society, 1973)Observations of the larger airborne sea-salt particles collected on Millipore filters at varying distances from the shore show that over the ocean and at distances greater than 8 km inland the relative frequency distribution ... -
Turbulence Spreading of Doppler Spectrum
(American Meteorological Society, 1973)Observations obtained by means of a zenith pointing, 3-cm pulsed-Doppler radar were used to estimate the turbulence spreading of the Doppler spectrum. This was done by comparing estimates of updraft velocity made by two ... -
Mesoscale History of a Small Patch of Clear Air Turbulence
(American Meteorological Society, 1973)Sequential analyses of data from a network of eight special rawinsonde stations 100 km apart demonstrate the important effects of mesoscale disturbances in a 2½-hr episode of light-to-moderate clear air turbulence (CAT). ... -
A Field Investigation of Dust Devils
(American Meteorological Society, 1973)A field observation program was conducted at El Mirage, Calif., to investigate some aspects of the interaction between dust devils and their environment. The outputs of sensors designed to measure vertical vorticity were ... -
Radiation, Temperature and Atmospheric Emissivities in a Polluted Urban Atmosphere at Hamilton, Ontario
(American Meteorological Society, 1973)Simultaneous measurements of global solar and incoming longwave radiation are presented for roof-top sites in a heavily polluted zone and relatively clean control sites in and around Hamilton. The measurements were taken ... -
Desert Aerosols Transported by Khamsinic Depressions and Their Climatic Effects
(American Meteorological Society, 1973)The mass of natural aerosol injected into the atmosphere by desert wind systems of the Khamsinic type has been estimated from long series of normal-incidence spectral solar radiation measurements and from synoptic analysis ... -
Experimental Variability in the Determination of the Energy Balance in a Deciduous Forest
(American Meteorological Society, 1973)The question of the experimental reliability of the use of the energy balance model in energy budget calculations in a deciduous forest has been studied. Data were collected from three towers located in a mixed hardwood ... -
A Numerical Analysis of Some Practical Aspects of Airborne Urea Seeding for Warm Fog Dispersal at Airports
(American Meteorological Society, 1973)A two-dimensional Eulerian model of warm fog dispersal by airborne hygroscope particle seeding is used to evaluate some practical aspects of urea seeding at airports. It is found that although turbulence and wind shear ... -
On the Strategy of Combining Coarse and Fine Grid Meshes in Numerical Weather Prediction
(American Meteorological Society, 1973)A simple model containing gravity waves of phase speed C and a basic current U is used to test the hypothesis that in a nested grid system of different mesh sizes a better computation on the fine grid results if the outer, ...
