Chemical Emission Scenarios and Detection Limits for Active Infrared RemoteSensing

摘要

This report presents results from the calculation of chemical emission rates fromvarious military and human activities: diesel electric generator exhaust, diesel exhaust from a missile transport vehicle, evaporation of light organic compounds from stored diesel, evaporation of spilled SCUD missile fuel, burning ammunition, burning sarin, human breath, cook stove exhaust, septic system and landfill emissions. Also presented are the results of Gaussian puff dispersion calculations of the different chemical compounds in each of the plume scenarios. These calculations allow concentration-pathlengths for the compounds to be determined, and, using this information, estimates are made of the infrared absorption cross sections for the compounds. Calculated infrared absorbance spectra of the compounds are also presented along with the absorbance spectra of compounds found in the atmosphere that may interfere with detection of the target compounds.
