Comparison of observed and simulated NAO signal in pollution transport from Europe (from Eckhardt et al., 2003). Map of residual NO2 vertical columns [1014 molecules cm−2] retrieved from GOME satellite observations for NAO+ minus NAO− composites during seven (1996–2002) winters (a). Same but in mg m-2 for a simulated European emission tracer with a 1-day lifetime (b). Superimposed as white lines are the correlation coefficients with the NAO index.
