| Zusammenfassung |
| We investigate the sensitivity of future spaceborne lidar measurements to
changes in surface methane emissions. We use surface methane observations
from nine European ground stations and a Lagrangian transport model to
infer surface methane emissions for 2010. Our inversion shows the strongest
emissions from the Netherlands, the coal mines in Upper Silesia, Poland, and
wetlands in southern Finland. The simulated methane surface concentrations
capture at least half of the daily variability in the observations,
suggesting that the transport model is correctly simulating the regional
transport pathways over Europe. With this tool we can test whether proposed
methane lidar instruments will be sensitive to changes in surface
emissions. We show that future lidar instruments should be able to detect a
50% reduction in methane emissions from the Netherlands and Germany, at
least during summer. |
