Sensitivity study of SO2 AMF and a special case study about SO2 emissions from Norilsk Smelter — •Mohammad Fahim Khokar1,2, Ulrich Platt1, Claire Granier2, Katey Law2, and Thomas Wagner1,3 — 1Institute for Environmental physics, Heidelberg, Germany — 2Service d’Aéronomie, Université Pierre and Marie Curie, Paris, France — 3Max-Planck Institut for Chemistry, Mainz, Germany
Radiative transfer modelling is best tool to convert slant column densities into vertically integrated columns. In this Study, TRACY II model is used for SO2 AMF calculation for different scenarios. SO2 AMF exhibited high dependency towards surface albedo, SO2 vertical profile, SZA, wavelength, clouds and aerosol.
Most of the non-ferrous metal ores contain sulfide and this is emitted as SO2 during the smelting process. Satellite observations of atmospheric sulfur dioxide (SO2) emitted from heavy metal smelting industry in Siberia, Russia is presented. Global Ozone Monitoring Experiment (GOME) data for the years 1996 to 2002 is analyzed using a DOAS-based algorithm with the aim of retrieving SO2 column amounts. Besides, decreasing trends in the atmospheric SO2 observed by GOME, these point sources are still a dominant source of anthropogenic SO2 emissions in the region. Enhanced SO2 column amounts are clearly identified from GOME and SCIAMACHY observations over the Siberian region.
