O3 chemiluminescence

The HAIS single channel NSF NCAR chemiluminescence instrument provides state of the art precision and time response (1-5 Hz) for a broad range of atmospheric science research campaigns. Observational experiments focusing on dynamical processes take advantage of the 1-channel ozone instrument. Example applications include investigation of trade-wind cloud system development during the CSET campaign, investigations of dynamical processes requiring tracers of stratospheric air composition (e.g., PREDICT, CONTRAST, ACCLIP, T-REX, and CGWaveS), and employed as a conserved micrometeorological cloud entrainment tracer (e.g., RICO, DYCOMS-II). When an airborne experiment includes a full atmospheric chemical payload, the HAIS 1-channel ozone instrument is incorporated into the 2-channel NO_x or NO_y instrument and supported by the NO_x and Ozone Measurement Group.
