TL;DR: In this paper, the authors used tunable diode laser absorption spectroscopy (TDLAS) to acquire airborne measurements of formaldehyde (CH 2 O) during the 2000 Tropospheric Ozone Production About the Spring Equinox (TOPSE) study.
Proceedings ArticleDOI
CAMS — Compact atmospheric multi-species spectrometer
TL;DR: In this paper, the authors present the design, development, and field performance of an airborne mid-IR spectrometer configured for the simultaneous sensitive detection of CH2O (∼40 pptv, 1 Hz) and C2H6(∼15pptv and 1 Hz).
Proceedings ArticleDOI
Advances in the performance assessment of a tunable diode laser absorption spectrometer for airborne measurements of CH/sub 2/O
TL;DR: An airborne tunable diode laser absorption spectrometer was deployed to measure CH/sub 2/O during NASA's 2004 Intercontinental Chemical Transport Experiment (ICTE) as discussed by the authors.
Proceedings ArticleDOI
Airborne atmospheric research using mid-infrared laser spectroscopy
TL;DR: In this paper, a new airborne spectrometer based upon a difference frequency generation (DFG) mid-IR laser source was deployed during the 2008 Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) campaign, and specific examples of its performance from this study will be discussed, as will the prospects for the detection of other trace gases.
