| Zusammenfassung |
| This paper presents an inverse method for inferring trace gas fluxes at high
temporal (daily) and spatial (model grid) resolution
from continuous atmospheric concentration
measurements. The method is designed for regional applications and
for use in intensive campaigns. We apply the method to a one month
inversion of fluxes over Europe. We show that the information added
by the measurements depends critically on the smoothness constraint
assumed among the source components. We show that the initial
condition affects the inversion for 20 days, provided one has enough
observing sites to constrain regional fluxes. We show that the impact
of the far-field fluxes grows throughout the inversion and hence a
reasonable global flux field is a prerequisite for a regional
inversion. |
