Paper Abstract

Cost-effective measurement techniques are required to assess environmental impacts of various emission sources in industry and agriculture. Fourier-transform-infrared-spectroscopy (FTIS) has great potential in this field due to the multicomponent nature of the measurements. Many compounds can be quantified from one single infrared spectrum. Gas releases from large compost heaps strongly contribute to the emission of greenhouse gases and other pollutants. Both open-path and extractive FTIS measurements were performed using the high-resolution K300 spectrometer operating inside a mobile laboratory for air pollution detection. The analysis software is based on a line-by-line radiative transfer algorithm and least-square fit procedures. Quantitative results of several measurement campaigns to analyze compost emissions are described. Emission rates are calculated from the concentration values and simultaneously recorded meteorological data using a Gaussian plume dispersion model.
