Aerolaser VUV

Slated for eventual retirement from the suite of NSF LAOF supported measurements, the Aero-Laser fluorescence CO instrument has served the NSF community for over 18 years, with a precision of 2 ppbv. The QCL instrument provides a better precision and time response, but at the cost of a larger footprint. Where possible, the QCL has replaced the VURF sensor for most NSF LAO community measurement requests.
