Photogrammetric Mapping for Highways: Western U.S.
Publisher: American Society of Civil Engineers
Abstract: This paper presents a brief history of photogrammetric mapping for highway activities in the Western States. Reasons for emphasis and development of techniques are discussed. Some of the problems encountered in the development ...
Radar Measurement of Velocities of Meteorological Scatterers
Publisher: American Meteorological Society
Abstract: Statistical properties of the field backscattered from a weather radar target are related to the velocity distribution of the scatterers comprising the target. The complete distribution of radial velocity components can ...
Some Radar Measurements of Turbulence in Snow
Publisher: American Meteorological Society
Abstract: The Doppler spectrum of snow contains information about the turbulent wind field in which the snow is embedded. The average spread of the spectrum is proportional to the kinetic energy per unit mass of air in turbulent ...
An Inversion Problem on Inferring the Size Distribution of Precipitation Areas from Raingage Measurements
Publisher: American Meteorological Society
Abstract: Given a long, continuous record of rain rate measured at a point on the ground, it is straightforward to select a threshold value of rate and note the duration of each event in which the threshold is exceeded. The distribution ...
Droplet Growth by Condensation and Coalescence in a Strong Updraft
Publisher: American Meteorological Society
Abstract: The growth of cloud droplets by condensation and coalescence in a strong updraft is investigated for different cloud conditions and different initial droplet distributions. Growth by coalescence is determined by solving ...
Mesoscale Fluctuations of Columnar Water Vapor
Publisher: American Meteorological Society
Abstract: During a 7-week period in the winter of 1986, a six-channel ground-based microwave radiometer was operated at a site near Halifax, Nova Scotia, as part of the Canadian Atlantic Storms Program. One of the quantities measured ...
