Initial Field Measurements of Atmospheric Absorption at 9–11 μm Wavelengths
(American Meteorological Society, 1979)A field adapted spectrophone system employing a tuneable CO2 laser source (over wavelengths 9.2?10.8 ?m) was used to measure atmospheric gaseous and particulate absorption at an isolated desert location in the southwestern ... -
Winter Storms over the San Juan Mountains. Part II: Microphysical Processes
(American Meteorological Society, 1979)Airborne observations of wintertime storms in southeastern Colorado have shown that the microphysical structure of those storms evolved in close relationship to the dynamical structure. The storms evolved from deep ... -
Dispersion of Airborne-Released Silver Iodide in Winter Orographic Clouds
(American Meteorological Society, 1979)Two flight plans were used for a seeding aircraft and a measurement aircraft in the study of silver iodide plume dispersion. An instantaneous line source and a continuous point source plume generation were simulated ... -
Winter Storms over the San Juan Mountains. Part III: Seeding Potential
(American Meteorological Society, 1979)The potential for snowfall augmentation in the San Juan Mountains of southwestern Colorado is considered. We show that the seeding criteria and delivery method used in the Colorado River Basin Pilot Project were not suited ... -
The Response of Superpressure Balloons to Gravity Waves
(American Meteorological Society, 1979)Analytic solutions of a balloon's response to simultaneous variations of the vertical wind speed and the density are obtained using Fourier expansion methods. It is assumed that density and wind are in phase quadrature. ... -
A Simple Physical Model to Estimate Incident Solar Radiation at the Surface from GOES Satellite Data
(American Meteorological Society, 1979)We present a model designed to estimate the incident solar radiation at the suface from GOES satellite brightness measurements in clear and cloudy conditions. In this simple physical model, the effect of Rayleigh scattering ... -
Atmospheric Water Content over the Tropical Pacific Derived from the Nimbus-6 Scanning Microwave Spectrometer
(American Meteorological Society, 1979)The scanning microwave spectrometer (SCAMS) aboard Nimbus-6 contains a 22.23 GHz water vapor channel and 31.65 GHz window channel for deriving integrated water vapor (precipitable water) and cloud liquid water through a ... -
Numerical Simulation of Ice-Phase Convective Cloud Seeding
(American Meteorological Society, 1979)A two-dimensional time-dependent cloud model which covers a region 19.2 km ? 19.2 km in the x and z directions with 200 m grid intervals, has been used to simulate silver iodide (AgI) seeding effects on strong convective ... -
A Critique of “Trees as a Local Climatic Wind Indicator”
(American Meteorological Society, 1979)This comment reviews many of the problems associated with using deformed vegetation as an indicator of mean annual wind speed and wind power potential. It critiques the Wade and Hewson (1979) use of a ?jackknife technique? ... -
Submicron Aerosol Particle Losses in Metalized Bags
(American Meteorological Society, 1979)Two new types of conducting bags were tested for aerosol particle storage and sampling, a 3M Company Velostat bag and a bag constructed from 3M Type 2100 Static Shielding Film. The half-lives of unipolar, unit-charged 0.025 ... -
A Color Camera for In Situ Photography of Cloud Particles
(American Meteorological Society, 1979)A technique is described for photographing airborne particles using small forward-scattering angles. The sample volume is defined as the region where collimated light beams of two different primary colors overlap. Images ... -

The Effects of Sunshine, Cloudiness and Haze on Received Ultraviolet Radiation in New York
(American Meteorological Society, 1979)Ultraviolet data from Rochester, Schenectady and Whiteface Mountain, New York, for the period November 1975-December 1977, have been studied to ascertain the importance of extraterrestrial ultraviolet (UV) radiation, ... -
Simultaneous Observation of Cool Cloud Liquid by Ground-Based Microwave Radiometry and Icing of Aircraft
(American Meteorological Society, 1979)An example of measurement of liquid water in a cool cloud deck by microwave radiometry and simultaneous observation of icing of aircraft is given. Implications in use of microwave radiometers for warning of icing conditions, ... -
Improved Drop Generators for Calibration of Drop Spectrometers and Use in Laboratory Cloud Physics Experiments
(American Meteorological Society, 1979)Drop generators have been developed at NCAR based on the ?wire egression? principle. They are outstanding in their flexibility and simplicity. Drops ranging in diameter from 6 ?m to 1 mm have been generated with one model. ... -
Comments on “Generalized Criteria for Seeding Winter Orographic Clouds”
(American Meteorological Society, 1979)No abstract available. -
Winter Storms over the San Juan Mountains. Part I: Dynamical Processes
(American Meteorological Society, 1979)The Colorado River Basin Pilot Project was conducted over the San Juan Mountains in southwestern Colorado and ran for five winter seasons, terminating in 1974?75. The objective of the project was to demonstrate the feasibility ... -
Quantitative Studies of Meteosat Water-Vapor Channel Data
(American Meteorological Society, 1979)In this paper, quantitative studies of water vapor Meteosat imagery, based on an accurate transmittance and radiance model are described. Using conventional radiosonde data, a linear relation between cloudless radiances ... -
An Index of Arizona Summer Rainfall Developed through Eigenvector Analysis
(American Meteorological Society, 1979)Summer rainfall in Arizona exhibits tremendous spatial variability due to topographic irregularities and the fact that convection is the dominant precipitation generating mechanism. As such it has proven difficult to ... -
Remote Sensing of Atmospheric Turbulence by Means of a Fast Optical Method: A Comparison with Simultaneous In Situ Measurements
(American Meteorological Society, 1979)In this paper we describe an experiment in which we measure the energy of the atmospheric turbulence up to an altitude of 20 000 m. The measurements have been performed simultaneously by a remote optical system attached ...
