Abstract

An airborne instrument using tunable diode lasers (TDL's) has been developed to make in situ measurements of trace atmospheric gases. The instrument performance for the measurement of ambient CO is characterized. A technique to suppress TDL excess noise is demonstrated that is expected to lead to an increase in the state-of-the-art sensitivity of the TDL differential absorption technique.
