Instrument

DFGAS
Difference Frequency Generation Absorption Spectrometer

The Difference Frequency Generation Absorption Spectrometer is an instrument designed to measure formaldehyde in the atmosphere. It measures the gas using an infrared laser. The instrument uses two lasers that operate at 1562nm and 1083nm. The instrument was used in multiple campaigns, and has since been replaced by the Compact Atmospheric Multispecies Spectrometer (CAMS).
