| Zusammenfassung |
| Surface-atmosphere exchange fluxes of CO2,
estimated by an interannual atmospheric transport inversion
from atmospheric mixing ratio measurements,
are affected by several sources of errors, one of which is
experimental errors.
Quantitative information about such measurement errors
can be obtained from regular co-located measurements
done by different laboratories or using different experimental techniques.
The present quantitative assessment is based on intercomparison
information from the CMDL and CSIRO atmospheric measurement programs.
We show that the effects of systematic measurement errors
on inversion results
are very small compared to other errors in the flux estimation
(as well as compared to signal variability).
As a practical consequence, this assessment justifies
the merging of data sets from different laboratories or
different experimental techniques (flask and in-situ),
if systematic differences (and their changes)
are comparable to those considered here.
This work also highlights
the importance of regular intercomparison programs. |
