Meteorological Instruments for Use Near the Ground: Their Selection and Use in Air Pollution Studies

Source

This paper deals with the instruments of primary importance in air pollution studies, those that are used to supply data for making dispersion estimates and to measure wind and temperature. Since air pollution—and, in its broader aspect, air quality—involves turbulence, the equipment employed to measure the fluctuations of the wind must have known dynamic characteristics. Also, the equipment used to measure temperature difference in relation to altitude must have known accuracies. Both wind- and temperature-measuring instruments should be given exposures that make the measurements representative of the physical phenomena at the location being studied.

Meterological instruments that do not provide data for dispersion estimates—generally considered of secondary importance—include equipment for the measurement of solar radiation, precipitation, humidity, atmospheric pressure, and visibility. A wide range of meterological equipment is now available to the individual or organization undertaking an air pollution study. The selection and use of this equipment is primarily dependent on the purpose of the investigation. To assist those concerned with meteorological study, guidelines are offered in terms of criteria, terminology, and instrument specifications, especially for wind and temperature sensors. Sources of equipment are also given, together with some comparisons of specifications.
