The UCATS system is three different instruments in one enclosure: a two-channel chromatograph with electron capture detectors (one measures N2O and SF6, the other measures CH4, H2 and CO), a tunable diode laser instrument for H2O, and a dual-beam O3 photometer.}, publisher={ORNL Distributed Active Archive Center}, author={Elkins, J.W. and Hintsa, E.J. and Moore, F.L.}, year={2019}, language={en}, }
