Description:
The report concerns the continuation of work in the development of a gas laser system for air pollution monitoring over long paths, a kilometer or more, using infrared absorption. Modifications to a bread-board system for simultaneous detection of O3, NH3, C2H4 and the addition of beam steering optics to give the system area monitoring capability are discussed. Operation for a two month period in St. Louis in conjunction with the RAPS program is also discussed. During this period O3 and NH3 were monitored at Site 103 in RAMS. Data comparing system performance with that of conventional monitors is presented along with the results of problem investigations.
