Reconstruction of motorway emission plumes by Long-Path-DOAS Tomography — •Kai Uwe Mettendorf, Pinhua Xie, Thomas Laepple, Christoph v. Friedeburg, Ulrich Platt und Irene Pundt — Im Neuenheimer Feld 229 69120 Heidelberg

We present here the geometrical setup and results from the first tomographic long-path DOAS experiment taking place in April/May 2001 next to a motorway. The setup includes two coaxial telescopes emitting light onto 8 retro reflecting arrays along and across the motorway. The arrays are mounted on two cranes positioned on both sides of the motorway 800 meters away from the telescopes. On each crane four arrays are placed at different altitudes: 10, 20, 30, and 40 meters. They are scanned successively by the telescopes, providing up to16 light paths. Slant column density results and reconstructed 1-2 dimensional concentration maps of the NO2 and SO2 emission plumes will be shown for different conditions.
