Langford, N. and Duxbury, G. and Wright, S. (2006) A compact quantum-cascade laser based spectrometer for monitoring the concentrations of methane and nitrous oxide in the troposphere. Applied Physics B: Lasers and Optics, 85 (2-3). pp. 243-249. ISSN 0946-2171 (http://dx.doi.org/10.1007/s00340-006-2384-x)

Abstract

A spectrometer, based on the frequency down-chirped radiation from a pulsed quantum-cascade laser, capable of detecting fluctuations in local ground level methane and nitrous oxide concentrations over a time scale of minutes, is presented. The applicability of this instrument to low-level atmospheric detection is demonstrated through sampling gases in two locations.
