Most sources of fugitive emissions are from multiple points rather than single point sources. So, open path area or perimeter monitoring provides more meaningful fugitive emissions data than an array of point sensors or a program of grab sampling. Point measurements may underestimate emissions because of missing locations with high gas concentrations, or conversely overestimate because they are located in areas of high concentrations. Grab sampling programs typically check only a small percentage of potential...

Airports, small and large, use noise and operations monitoring systems to reduce the noise of flight operations in the surrounding community. Noise monitoring is generally used to evaluate noise abatement programs and to develop aircraft departure and arrival procedures that minimize the impact of aircraft noise based upon altitude, flight path, and time of day. Noise monitoring is linked with radar tracking so that specific aircraft can be identified when noise limits are exceeded and so...
