Open Path Remote Sensing

Source/Emissions Characterization

Objectives
EPA makes use of the capabilities of remote sensing equipment to measure fine particulate matter and global warming precursor pollutants from fugitive emission sources. Infrared FTIR and diode laser equipment are used to measure ammonia, a fine particulate matter precursor, from animal farms, storage facilities and urban traffic. Modified FTIRs are being deployed to measure vehicular formaldehyde at roadside. FTIR and diode laser equipment also is used to measure methane emissions from landfills. Ultraviolet spectra equipment is now being deployed to determine mercury emissions from chlor-alkali plants.
