COLD2
Carbon Oxide Laser Detector 2

The Carbon Oxide Laser Detector 2 (COLD2) is an in situ airborne quantum cascade laser spectrometer. It measures carbon monoxide (CO) at 4.7 microns in the upper troposphere and lower stratosphere. It also measures nitrous oxide (N2O). COLD2 has a measurement frequency of 1 Hz and a sensitivity of approximately 2 ppbv. COLD2 can also be configured to operate on balloons.
