Abstract
A new system for NO2 detection has been developed for use on the NASA ER-2 aircraft. The system converts NO2 to NO using UV photolysis with the NO product subsequently detected with an on-board chemiluminescenc e detector. The new system is compact, light weight, has high time res olution (similar to 1 s), and is significantly more efficient then som e previous designs. Details of the system design and airborne performa nce are discussed.
