182 G.J.Roelofs, J. Lelieveld and R.van Dorland “A three-dimensional chemistry/general circulation model simulation of anthropogenically derived ozone in the troposphere and its radiative climate forcing” J. of Geoph. Res. 102, D19, 23389-23401, 1997 Model calculations with the European Center Hamburg Model-ECHAM, with pre-industrial and contemporary emissions Block-Kurs Luftchemie <strong>Berlin</strong>, 13-17 März 2006
183 Block-Kurs Luftchemie Radiative forcing sensitivity of global surface temperature to changes in vertical ozone distribution. The heavy solid line is a least squares fit to onedimensional model radiativeconvective equilibrium results computed for 10 Dobson unit ozone increment added to each atmospheric layer. Ozone increases in region I (below ≈ 30 km) warm the surface temperature. No feedback effects are included in the radiative forcing. From: Lacis et al., 1990 <strong>Berlin</strong>, 13-17 März 2006
