Abstract

The Mobile Atmospheric Pollutant Mapping System (MAPM) has been developed and demonstrated at JPL with funding from the U. S. Air Force. MAPM was designed around a pair of hybrid TEA CO₂ lasers to enable DIAL measurements to be made rapidly, to long range, and with high accuracy. This paper will describe the system, discuss the data processing algorithms, present some data on signal averaging, on concentrations of water vapor and trace molecular species, as well as review the literature on the water vapor absorption coefficients at CO₂ laser line frequencies.
