  14. Compare with Carbon Tracker

  15. Green=NH, Red=SH, Black=Flux

  16. Fluxes from level 1 to 5

  17. Green=NH, Red=SH, Black=Flux

  18. Summary • Data shows evidence for enhanced transport • Models shows CO2 transport in high troposphere • Transport sensitive to Kyy (small scale processes)

  19. Backup Slides

  20. Table 1 Of the nearly 7 GT-C/yr net CO2 source created in N.H. 75% is transported into S.H. and 48% is absorbed by the surface of S.H. Sensitivity Tests, 20% reduction of : Kyy => 10% decrease of the cross equator flux Kzz => 4% PSI => 1% Distribution of S.H. sink 0-30 deg. S. 75% (source) 30-60 deg. S. 30% 60-90 deg. S. -5%
