Abstract: A method for characterizing gas emissions includes sampling each of a plurality of sectors having a common geographic center. For each sector, a first laser beam is transmitted from the geographic center to a first retroreflection location, where it is retroreflected into a first retroreflected beam. Near the geographic center, the first retroreflected beam is measured to obtain a first absorption. A second laser beam is then transmitted from the geographic center to a second retroreflection location, where it is retroreflected into a second retroreflected beam. Near the geographic center, the second retroreflected beam is measured to obtain a second absorption. The first and second retroreflection locations are both located within the same sector. First and second concentrations are determined from the first and second absorptions and processed to determine emission information about a known or potential gas source whose source lies within the sector.
