IR Camera (HAWK/GasFindIR)
VOC leaks appear as dark clouds (colors can be
reversed).
The IR Camera is an excellent and relatively inexpensive tool for finding
leaking organic gases, however it cannot quantify the emission rate.

Differential Absorption LIDAR (DIAL)
DIAL does not require mirrors. Laser light reflects
off of particles in the air and returns to the
detector.
DIAL quantifies emissions with
wind speed and a vertical concentration
map.

Note that many emissions are far
above ground level.
Solar Occultation Flux (SOF)
Texas City Industrial Complex
SOF uses the sun as its light source to a mobile FTIR
detector mounted in a van.

SOF “Box”
Solar Occultation Flux (SOF)SOF uses the sun as its light
source to a mobile FTIR detector mounted in a van.
SOF quantifies emissions with
wind speed and a material
balance around the “SOF Box”.
