Determination of emission sources by remote sensing

摘要

In the SANA programme unknown emission sources are inspected and emission rates of different gas releases are validated using FTIR-spectroscopy. Gaseous emission rates from industrial and agricultural areas, highways, garbage deposits, open-cast lignite minings, compost heaps and an ensemble of small-building smoke stacks are estimated. CO_2, N_2O, CH_4, NH_3, CO, NO, H_2O, and HCHO are determined from measured absorption spectra in extended area plumes. Effluent concentrations such as CO, CO_2, H_2O, NO, N_2O, NO_2, SO_2, and HC1 from smoke stacks and flares as well as temperature of plumes are quantified from measured emission spectra with the multi-component spectra analysis software MAPS developed at the IFU. Mass fluxes were determined combining a FTIR-spectrometer and a Doppler-lidar which measured the chimney plume velocity.
