Argus
Argus Tunable Diode Laser Instrument

Argus is a two-channel, tunable diode laser instrument that was developed at NASA Ames Research Center. Argus collects in situ measurements of carbon monoxide (CO), nitrous oxide (N2O), and methane (CH4) in the atmosphere by using second harmonic spectroscopy. Argus operates in the mid-infrared range (3.3 and 4.7 micrometers) and has an accuracy of about 3% for data rates of 0.1 to 0.5 Hz. Argus is ideal for small payload platforms such as balloons and uncrewed aerial vehicles (UAV) due to its lightweight and compact design.
