| Zusammenfassung |
| We present net emission estimates of CH4 and N2O of The
Netherlands based on measurements conducted during the period of May 2006 to
April 2009 at station Lutjewad, The Netherlands (6°21' E,
53°24' N, 1 m a.s.l.). 222Radon mixing ratios were applied as an indicator
for vertical mixing and long-range air mass transport and used to calculate
the net surface fluxes from atmospheric mixing ratios of CH4 and
N2O. Our study shows that our measurement site Lutjewad is well-suited
to measure emissions from The Netherlands and validation of the national
inventories using the 222Radon flux method. Since this study is purely
observation-based it is independent from inventories or atmospheric models.
Our results are compared to the national inventories as reported to the
UNFCCC. We found net emissions of: (15.2±5.3) t km−2 a−1 for
CH4 and (0.9±0.3) t km−2 a−1 for N2O. These values
are lower than the inventory-based emissions (2006-2008 averages) of
(18.3±3.3) t km−2 a−1 for CH4, and
(1.3±0.6) t km−2 a−1 for N2O, but
the differences are insignificant. |
