“…The Brookhaven gustiness-classification system [1], which does not require a detailed analysis of the wind trace, is an excellent example of the use of standard equipment. Also, instruments have been designed, and at least one is commercially available, specifically for the purpose of giving data on gustiness.…”

Significant requirements in wind-instrumentation or -measurement techniques are briefly reviewed with respect to the operational or research function in which they are employed. It is concluded that sensing devices can be obtained or have been devised which are, in principle, satisfactory for the field investigation of most practical and many theoretical problems arising in air-pollution studies. However, devices for rapid output-data reduction, transformation, or manipulation in a form to be of greatest utility are badly needed, preferably as integral parts of the wind-instrumentation setup itself. Progress in developments in this direction is reported and future needs pointed out.

“…Rather than emphasize the instrumental methods, many authors adapted and presented the method to be used with available meteorological observations. 42 " 46 Prior to this development, Singer and Smith 47 used the trace from a wind vane to define "Brookhaven gustiness classes." These classes were also related to dispersion parameters used in Gaussian dispersion equations.…”

There are many requirements for dispersion models in the Clean Air Act Amendments of 1977 including prevention of significant deterioration, air quality maintenance plans, and new source permits. The historical perspective of dispersion modeling includes both theoretical and practical developments, rural and urban field studies including tracer studies, plume rise, and urban modeling. Photochemical modeling includes both grid point and trajectory models. Off-the-shelf models include level terrain models for elevated point sources, urban point and area sources, and transportation sources; and complex terrain models for point sources. Models are needed for photochemical pollutants, sulfates, and nitrates; they should treat long range transport, topographic effects, build-up of urban concentrations, and aerodynamic downwash. Emphasis is placed herein upon proper interpretation of vertical temperature structure measurements, and the difficulties in determining the magnitude and locations of the highest and second highest concentrations in a year. Modeling improvements can be expected with representative on-site measurements of input parameters, and improved dispersion parameter schemes which must be verified with appropriate field investigations. Terms related to model evaluation are defined. A primary source of error, in comparing model estimates with monitored air quality, is not including the actual change of wind direction with height which determines elevated plume position. Measures for model evaluation will differ depending upon model use. The paper concludes asking for 1) encouragement of model development, 2) improvement of model inputs through on-site measurements, and 3) detailed field investigations.Mr. Turner is presently on assignment from the National

“…Mean hourly wind direction, wind speed and gustiness (Singer and Smith) 12 measurements were provided by LILCO from stations at Hicksville (east of Stewart Ave. on Figure 1), Northport, and Port Jefferson. Similar data plus temperature difference measurements were available from Shoreham (on the shore north of BNL).…”
