The Picarro G2401-mc utilizes wavelength scanned cavity ring down spectroscopy, a technique wherein the exponential decay of optical extinction within a resonant cavity is modified by molecular absorption.
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.
Slated for eventual retirement from the suite of NSF LAOF supported measurements, the Aero-Laser fluorescence CO instrument has served the NSF community for over 18 years, with a precision of 2 ppbv.
