ARGUS
Definition
- ARGUS is a two channel, tunable diode laser instrument set up for the simultaneous, in situ measurement of CO (carbon monoxide) and CH4 (methane) in the troposphere and lower stratosphere. The instrument measures 40 x 30 x 30 cm and weighs 21 kg. An auxiliary, in-flight calibration system has dimensions 42 x 26 x 34 cm and weighs 17 kg. The instrument is an absorption spectrometer operating in rapid scan, second-harmonic mode using frequency-modulated tunable lead-salt diode lasers emitting in the mid-infrared. (en)
