Abstract
This work presents a system concept for remote emission sensing, focusing of the design and validation of a calibration-free wavelength modulation spectroscopy (CF-WMS) approach. We show the applica-bility of a CF-WMS system for the detection of CO2 emissions of on-road vehicles with laboratory vali-dation measurements as well as first field tests.
