The Quantum Cascade Laser System (QCLS) is an airborne and ground-based in situ spectrometer developed by Harvard University and Aerodyne Research. QCLS comprises two instruments: the Harvard QCL DUAL and the Harvard QCL CO2. The QCL DUAL uses two thermoelectrically cooled QCL light sources to measure carbon monoxide (CO) at 4.59 microns and 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) at 4.32 microns. QCLS operates at a measurement frequency of 1 Hz.
