متن کاملSources and sinks of ammonia within an oilseed rape canopy
Within-canopy profiles of ammonia (NH3) and measurements of the canopy turbulence characteristics were used to calculate the vertical source/sink density profile of NH3 and sensible heat in a mature oilseed rape (Brassica napus) canopy. For the analysis, the inverse Lagrangian technique (ILT) based on localized near-field theory was used. Turbulence was measured with a standard ultrasonic anemo...
متن کاملIntercomparison of ammonia measurement techniques at an intensively managed grassland site (Oensingen, Switzerland)
As part of a field campaign in the framework of the NitroEurope project, three different instruments for atmospheric ammonia (NH3) measurements were operated sideby-side on a managed grassland site in Switzerland: a modified Proton Transfer Reaction Mass Spectrometer (PTRMS), a GRadient of AErosol and Gases Online Registrator (GRAEGOR), and an Automated Ammonia Analyzer (AiRRmonia). The modifie...
