The Quantum Cascade Laser System (QCLS) is an airborne and ground-based in situ spectrometer system developed by Harvard University and Aerodyne Research. QCLS includes two instruments: the Harvard QCL DUAL instrument and the Harvard QCL CO2 instrument. The QCL DUAL uses two thermoelectrically cooled QCL light sources to measure carbon monoxide (CO) at 4.59 microns, as well as methane (CH4) and nitrous oxide (N2O) at 7.87 microns. The QCL CO2 instrument employs a single QCL light source to measure carbon dioxide (CO2) concentrations at 4.32 microns. QCLS operates at a measurement frequency of 1 Hz.
