The presently disclosed subject matter relates to methods, systems, and computer program products for monitoring for low vapor pressure noxious compounds in the atmosphere. More particularly, the presently disclosed subject matter relates to an active, modulated open-path infrared method, system, and computer program product for detecting, identifying, and quantifying one or more low vapor pressure noxious compounds in the atmosphere, wherein the one or more low vapor pressure compounds can be present in the vapor phase, the aerosol phase, adsorbed on airborne particulate matter, and combinations thereof. |
