Heterogeneous Interaction of Ozone, NO? and N^Og with Soot Aerosol A contribution to subproject CMD S. Kamm, O Mohler, K-H Naumann, H Saathoff and U. Schurath Forschungszentrum Karlsruhe, Institut fur Meteorologie und Klimaforschung, Postfach 3640, D-76021 Karlsruhe, Germany Introduction Atmospheric soot concentrations range from 0.002 \ig/m* in the stratosphere up to 40 ng/nr* in the polluted urban troposphere. Due to its irregular agglomerate structure soot aerosol offers a large surface for interactions with reactive trace gases like ozone. Recent laboratory studies and model results indicated a possible effect of soot surface reactions on the nitrogen partitioning in the troposphere (Kalberer et al, 1996; Hauglustaine et al, 1997; Rogaski et al, 1997) and on the stratospheric (Lary et al, 1997) and tropospheric ozone concentrations (Bekki et at., 1997). However, the mo
