| Zusammenfassung |
| We report here top-down emissions estimates for an African megacity. A
boundary layer circumnavigation of Lagos, Nigeria was completed using the
FAAM BAe146 aircraft as part of the AMMA project. These observations
together with an inferred boundary layer height allow the flux of pollutants
to be calculated. Extrapolation gives annual emissions for CO, NOx, and
VOCs of 1.44 Tg yr−1, 0.03 Tg yr−1 and 0.37 Tg yr−1
respectively with uncertainties of +250/−60%. These inferred
emissions are consistent with bottom-up estimates for other developing
megacities and are attributed to the evaporation of fuels, mobile combustion
and natural gas emissions. |
