This paper describes a technique for modelling of rain drop size distributions at Calcutta in terms of negative exponential function, from the measurements of rain rate and attenuation over a dual wavelength LOS link at millimeter and optical frequencies. The DSD model obtained is then used to determine the attenuation at 94 GHz, for comparison with experimentally obtained attenuation at 94 GHz. This is also compared with the attenuation calculated by considering other experimentally obtained DSD models. The best fit negative exponential distribution function (modified M-P model) is presented along with some other experimentally obtained and reference models.read more

The influence of meteorological variables on the performance of outdoor wireless local area networks
TL;DR: A clear relation between the weather and the performance of an outdoor WLAN is shown, extracted from a correlation analysis between several meteorological variables and the control and management frames of the data link layer of a WLAN at the Universitat Politècnica de València campus.
Measurements of DSD Second Moment Based on Laser Extinction
TL;DR: In this paper, the extinction of a laser passing through rain (or dust in the rocket case) yields an estimate of the 2nd moment of the particle cloud, and rainfall drop size distribution (DSD) in the terrestrial meteorological case.

The physics of clouds
F. H. Ludlam,Basil John Mason +1 more
TL;DR: In the last fifteen years there has been a surge of activity in this science under the stimulus of development in civil and military aviation as discussed by the authors, and the growth of cloud physics during this period has been fostered not only by this general invigoration, but also by recognition of the practicability of exerting some influence upon the behaviour of clouds and their capacity for producing rain, hail, lightning and other meteorological phenomena.

The relation of raindrop-size to intensity
J. Otis Laws,Donald A. Parsons +1 more
TL;DR: The applicability of such results to conditions of natural rainfall has been thrown in doubt as discussed by the authors, and the results have been found to be affected by the drop-size and velocity of the artificial rains applied.

Modeling of a tropical raindrop size distribution for microwave and millimeter wave applications
TL;DR: In this article, the authors describe the modeling of the average raindrop size distribution measured at Ile-Ife, a tropical station in South Western Nigeria, using a method of moment regression, which allows a single lognormal function to be accurately fitted over the entire range of rain rates measured, a convenient result for rain attenuation and scattering applications.
