<p>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 various spatial and temporal scales are required. Infrared laser absorption spectroscopy is often the method of choice, offering outstanding performance and reliability. Most frequently, however, this technology is used in a “one-species-one-instrument” solution because of the narrow spectral coverage of DFB-lasers. This can be overcome by combining several Quantum Cascade Lasers (QCLs), providing unique solutions in compact laser absorption spectrometers for environmental monitoring of multiple species in a single instrument.</p><p>We combined multiple DFB-QCLs into a single, compact laser absorption spectrometer to measure up to ten different compounds. We present simultaneous atmospheric measurements of the greenhouse gases CO<sub>2</sub>, N<sub>2</sub>O, H<sub>2</sub>O and CH<sub>4</sub>, and the pollutants CO, NO, NO<sub>2</sub>, O<sub>3</sub>, SO<sub>2</sub> and NH<sub>3</sub> with a single instrument. Furthermore, the instrument performance, first field results and comparison to standard air-quality and greenhouse gas monitoring instrumentation are discussed. The results demonstrate that spectrometers using QCLs can serve as an all-in-one solution for environmental monitoring stations replacing up to seven instruments at once. Furthermore, due to their reduced size and robustness, they can be used on mobile platforms, opening up new applications of air quality and greenhouse gas monitoring in cities.</p>

Automated Measurement System

Abstract. A novel automated enclosure for protecting solar-tracking atmospheric instruments was designed, built, and tested under various weather conditions. A complete automated measurement system, consisting of a compact solar-tracking Fourier Transform spectrometer (EM27/SUN) and the enclosure, has been deployed in central Munich for greenhouse gas monitoring for one year and withstood all critical weather conditions, including rain, storm, and snow. It has provided continuous ground-based measurements of column-averaged concentrations of CO2, CH4, O2 and H2O. The enclosure protects the instrument from harmful environmental influences while allowing for open path measurements in sunny weather conditions. The newly developed and patented cover, a key component of the enclosure, permits unblocked solar measurements, while reliably protecting the instrument within less than 6 seconds. This enables very dynamic decisions about taking measurements, and thus increases the amount of data samples. The presented enclosure leads to a fully automated measurement system, which collects data whenever possible without any human interaction. The functionalities of the enclosure give full control over the EM27/SUN. It provides the fundament for a long-term greenhouse gas monitoring sensor network.
