Simultaneous eddy flux monitoring of 10 greenhouse gases and air pollutants with a single instrument
Monitoring of trace gas fluxes and greenhouse gas fluxes is key to understand the interaction between atmosphere, plants, and soil and therefore to improving our understanding of the climate system in general.The complex flux systems require measurem

Urban air pollution and greenhouse gas emissions are two closely linked problems. They can be attributed to a variety of sources, such as transportation and buildings, waste management and agricultural production, natural events such as forest fires

We report on the dynamic behavior of dual-wavelength distributed feedback (DFB) quantum cascade lasers (QCLs) in continuous wave and intermittent continuous wave operation. We investigate inherent etaloning effects based on spectrally resolved light-

Observation of air pollutants and greenhouse gases with high selectivity and sensitivity is of great importance for our understanding of their sources and sinks. For air pollution modelling and validation of emission inventories measurements at vario

We review the progress of multi-wavelength distributed feedback (DFB) quantum cascade lasers (QCLs) as sources for broadband mid-infrared (mid-IR) spectroscopy. While it is possible to tune the emission wavelength of DFB QCLs in a frequency range of

Mid-IR spectroscopy using QCLs allows sensitive, selective, and fast detection of trace gases. Recent developments, including dual-wavelength QCLs, create tantalizing options for compact, multi-species analysis in industrial and environmental applica

Instrumentation for environmental monitoring of gaseous pollutants and greenhouse gases tends to be complex, expensive, and energy demanding, because every compound measured relies on a specific analytical technique. This work demonstrates an alterna
