Aerosol Extinction at 500 nm in Urban and Rural Air at Milwaukee in April 1976
(American Meteorological Society, 1979)Aircraft measurements of aerosol size distributions were used to calculate aerosol extinction coefficients at 12 flight altitudes over an urban and a rural site at Milwaukee. Analysis of vertical-horizontal cross sections ... -
Overestimates of Entrainment From Wetting of Aircraft Temperature Sensors in Cloud
(American Meteorological Society, 1979)Temperature measurements from aircraft, taken with a reverse flow sensor and Rosemount probe, were compared in a penetration through a cloud to determine the effect of sensor wetting on the deduced entrainment. The temperature ... -
Atmospheric Liquid Water Content Derived from Parameterization of Nimbus 6 Scanning Microwave Spectrometer Data
(American Meteorological Society, 1979)An empirical-theoretical method to determine liquid water content and water vapor amount over land surfaces from Nimbus 6 SCAMS channels is described. The method is based on parameterization of the resulting calculations ... -
The Microstructure of Clouds in the High-Frequency Hail Area of Kenya
(American Meteorological Society, 1979)During June 1977 ground-based measurements of the CCN spectrum were made twice daily near Kericho, Kenya, and two flights were flown in that region to investigate the microstructure of the clouds. Both the CCN and the ... -
VHF Radar Observations of a Frontal Passage
(American Meteorological Society, 1979)Measurements of the vertical structure of the troposphere were carried out using a VHF radar during the passage of a warm front. The radar records indicated a descent of layers of enhanced humidity and temperature variations ... -
Revised Estimates for Continuous Shoreline Fumigation
(American Meteorological Society, 1979)A model is developed to describe the dispersion of pollutants in a coastal area when stable air masses are transported inland. It is assumed that a convective mixed layer develops over land, the height of which increases ... -
Maximum Likelihood Estimation of Fourier Coefficients to Describe Seasonal Variations of Parameters in Stochastic Daily Precipitation Models
(American Meteorological Society, 1979)Fourier series are convenient expressions for the seasonally fluctuating values of parameters in stochastic models of precipitation. Least-squares methods are often used to estimate the Fourier series coefficients, but ... -
The Backscatter Matrix of Ice Samples: Its Relation to the Identification of Hail by Radar
(American Meteorological Society, 1979)Measurements of the backscatter matrix, including phase, have been made at 2.86 GHz on blocks of ice intended to approximate oblate and prolate spheroids with axial ratios of 0.6 and 0.8. For 2.5<ka<4.5 respective cancellation ... -
Electrets Used in Measuring Rocket Exhaust Effluents from a Space Shuttle Model
(American Meteorological Society, 1979)The purpose of this experimental research was to investigate the use of electrets as a measuring device to measure the hydrogen chloride concentrations of rocket exhaust effluents. The word electret was derived by Heaveside ... -
Receiver Bandwidth Effect on Reflectivity and Doppler Velocity Estimates
(American Meteorological Society, 1979)Probert-Jones' radar equation assumes receiver bandwidth large compared to the reciprocal of the transmitted pulse width τ. The advent of coherent radars with precise transmitter frequencies allows consideration of receiver ... -
Submicron Aerosol Losses in Aluminized Mylar Bags
(American Meteorological Society, 1979)Aluminized Mylar bags are used by many researchers to store aerosol samples for later analysis. Our results show that the rate of deposition of unipolar unit-charged aerosols to the walls can be extremely high and is ... -
A Parameterization of the Evaporation from Nonsaturated Surfaces
(American Meteorological Society, 1979)The parameterization of evaporation proposed by Priestley and Taylor (1972) is modified to take account of nonsaturated surfaces. It is suggested that evaporation can be expressed as a function of net radiation, air ... -

The Crop Moisture Index: Unnatural Response to Changes in Temperature
(American Meteorological Society, 1978)A sensitivity study conducted on the Crop Moisture Index revealed that in some cases the index indicates wetter conditions as temperature increases. The unnatural response is due to the formulation of the evapotranspiration ... -
Comparison of Low-Level Cloud Motion Vectors and Moored Buoy Winds
(American Meteorological Society, 1978)Moored buoy wind measurements made at 3 m height at three sites (8°27?N, 150°45?W; 0°, 150°W; 0°, 125°W) in the central equatorial Pacific during 1976 and 1977 were compared with satellite-derived low-level (?1 km) cloud ... -
Rocket Effluent: Its Ice Nucleation Activity and Related Properties
(American Meteorological Society, 1978)To investigate the possibility of inadvertent weather modification from rocket effluent, aerosol samples were collected from an instrumented aircraft subsequent to the Voyager I and II launches. The aerosol's morphology, ... -

Monte Carlo Simulation of Turbulent Atmospheric Transport and Comparisons with Experimental Data
(American Meteorological Society, 1979)In a previous paper Peterson presented measurements of the 41Ar emitted continuously into the atmosphere from a reactor at the Brookhaven National Laboratory. Here, calculated results obtained with the Monte Carlo atmospheric ...
