Remote Sensing of Pollutants in Gas Plumes by Infrared Emission Radiometry-Spectroscopy.

摘要

Results of work on the application and development of quantitative methods for the determination of pollutants from emission sources by remote sensing,combining infrared radiometry and spectroscopy are presented and the method proved feasible. Generalized temperature and concentration models,based on the theory plus certain empirical factors have been developed and their applicability demonstrated. Field measurements at 65 m. distance on gas fired power plant plumes at temperatures 500 - 600K were made and CO,NO and NO2, CH4+saturates,and H2H4+ unsaturates,concentrations were determined. Extension of the method to temperature and concentration gradients and fluctuations in plumes due to chemical reactions,and measurements at greater distances appear to be feasible.
