Abstract
Attention is given to an airborne UV-DIAL being developed in response to major unresolved issues concerning ozone nonattainment, the single most important air quality problem in the U.S. The system itself, its testing and characterization, and some of the principal applications of the system as an environmental monitoring tool are described. UV-DIAL will allow for the concurrent measurement of range-resolved concentrations of ozone and sulfur dioxide gases in the lower three to four kilometers of the troposphere. Achievable cell resolution will be between 50 and 200 m in the vertical and 500 and 1000 m in the horizontal; the required averaging of 'off-line' and 'on-line' signal pairs prior to the DIAL calculations to achieve acceptable SNRs will largely determine the size of these cells. Simulations conducted to examine the consequences of statistical and systematic errors on the derived gaseous pollutant concentrations and to select suitable algorithms for the detailed data processing showed that the precision of the calculated concentrations for both ozone and sulfur dioxide was generally acceptable with regard to statistical errors.
