Abstract:

The Mobile Atmospheric Pollutant Mapping MAPM System is a dual CO2 laser, differential absorption lidar DIAL system designed and developed for the remote, range-resolved measurement of concentrations of trace molecular species and aerosols optical depths. In the DIAL technique, atmospheric aerosols provide the backscatter for a pulsed laser beam one laser is tuned to an absorbing wavelength of the molecular species of interest the other is tuned to a nearby non-absorbing wavelength. The derivative of the logarithm of the ratio of the two signals is used to determine the gas concentration. Heterodyne detection is employed with MAPM to enable long-range measurements. MAPM has been demonstrated with ambient water vapor, ozone, and aerosols, with a free release of ethylene, and with various organic solvent vapors in a sample chamber.
