aafso2

The sulfur dioxide analyzer measures sulfur dioxide based on absorbance of ultraviolet (UV) light at one wavelength by SO2 molecules that then decay to a lower energy state by emitting UV light at a longer wavelength. The instrument sampled from a trace gas inlet on the starboard side of the fuselage.
