Other claims from this paper (8)
- Observation The mean NH3 flux from the beech forest was 0.087 ± 0.19 μg NH3-N m−2 s−1.
- Observation Emission was measured in 57.7% of the NH3 fluxes.
- Observation Deposition was measured in 19.5% of the NH3 fluxes.
- Method / resource Modelled NH3 concentrations from DAMOS fit the measured concentrations before leaf fall.
- Method / resource Modelled NH3 concentrations are too low during and after leaf fall.
- Association Diurnal variations in measured NH3 concentrations were related to meteorological conditions and forest phenology.
- Recommendation Emissions from deciduous forests should be included in model calculations of atmospheric NH3.
- Recommendation An accurate description of ammonia fluxes over forest ecosystems requires a dynamic description of atmospheric and vegetation processes.
