Abstract Remote sensing methods offer various advantages over contact measurement methods both for characterizing the gaseous and particulate air pollutants emitted by different types of sources and for verifying that established emission standards are being met by regulated industries. Two such instrumentation systems are in routine use for characterization studies: a mobile pulsed ruby lidar system measures stack plume opacity with an accuracy comparable to an in-stack transmissometer; and a mobile high resolution (0.1/cm) infrared spectrometer system measures multiple gaseous species concentrations in a longpath absorption mode or in a single-ended emission mode with near-laboratory accuracy. A laser-Doppler velocimeter system for measuring the velocity of stack plumes and winds aloft has recently been obtained. Several systems particularly aimed at meeting the measurement needs of enforcement personnel are under evaluation. Tuneable laser systems for use in the longpath absorption mode and in the differential absorption lidar mode are in various stages of development. Research programs are underway to determine the feasibility of remotely measuring particulate size distributions and pollutant (gases and particles) mass emission rates. This paper presents results obtained with the instruments currently in use and summarizes the current state of development of the various other systems.
