متن کاملNitrous oxide emissions from managed grassland: a comparison of eddy covariance and static chamber measurements
Managed grasslands are known to be an important source of N2O with estimated global losses of 2.5 Tg N2ON yr−1. Chambers are to date the most widely used method to measure N2O fluxes, but also micrometeorological methods are successfully applied. In this paper we present a comparison of N2O fluxes measured by non-steady state chambers and eddy covariance (EC) (using an ultra-sonic anemometer co...
متن کاملFirst eddy covariance flux measurements by PTR-TOF.
The recently developed PTR-TOF instrument was evaluated to measure methanol fluxes emitted from grass land using the eddy covariance method. The high time resolution of the PTR-TOF allowed storing full mass spectra up to m/z 315 with a frequency of 10 Hz. Three isobaric ions were found at a nominal mass of m/z 33 due to the high mass resolving power of the PTR-TOF. Only one of the three peaks c...
متن کاملNitrous Oxide Flux from a Heterogeneous Agricultural Landscape: Analysis of Source Contribution by Eddy Covariance and Static Chambers
Eddy covariance and static chambers are different-scale methods for monitoring agricultural N2O that, when used together on heterogeneous agricultural landscapes, can help identify flux sources and sinks and evaluate the effect of management interventions on landscape-scale N2O emissions. This study compared the N2O flux data obtained by eddy covariance and static chambers during a short-term N...
