CAMS
Compact Atmospheric Multispecies Spectrometer

The Compact Atmospheric Multispecies Spectrometer (CAMS) is an in situ airborne spectrometer developed by the University of Colorado. CAMS uses mid-IR (3.53 μm) absorption spectroscopy to measure formaldehyde and ethane in the atmosphere. It utilizes difference-frequency generation (DFG) to produce the mid-IR light by mixing two near-IR (1562 and 1083 nm) laser sources. CAMS provides high precision measurements at a sampling frequency of 1 Hz.
