Summary: | A method for characterizing gas emissions includes measuring first and second optical beams to generate first and second absorption signals, respectively. Each of the optical beams is transmitted from a center point and retroreflected back to the center point. Paths of the optical beams define boundaries of a sector. Based on the absorption signals, an emission rate of a gas from within the sector is determined. If the emission rate exceeds a threshold, a third optical beam is measured to generate a third absorption signal. The third optical beam is transmitted from the center point and retroreflected back to the center point. The third optical beam propagates along a path that divides the sector into first and second subsectors. Based on the first, second, and third absorption signals, a location of a source of the gas is identified as being within the first subsector or the second subsector. |
