Abstract

A major international experiment on ammonia (NH³) biosphere-atmosphere exchange was conducted over intensively managed grassland at Braunschweig, Germany. The experimental strategy was developed to allow an integrated analysis of different features of NH³ exchange including: a) quantification of nearby emissions and advection effects, b) estimation of net NH³ fluxes with the canopy by a range of micrometeorological measurements, c) analysis of the sources and sinks of NH³ within the plant canopy, including soils and bioassay measurements, d) comparison of the effects of grassland management options on NH³ fluxes and e) assessment of the interactions of NH³ fluxes with aerosol exchange processes. Additional technical objectives included the inter-comparison of different estimates of sensible and latent heat fluxes, as well as continuous-gradient and Relaxed Eddy Accumulation (REA) systems for NH ³ fluxes. The prior analysis established the spatial and temporal design of the experiment, allowing significant synergy between these objectives. The measurements were made at 7 measurement locations, thereby quantifying horizontal and vertical profiles, and covered three phases: a) tall grass canopy prior to cutting (7 days), b) short grass after cutting (7 days) and c) re-growing sward following fertilization with ammonium nitrate (10 days). The sequential management treatments allowed comparison of sources-sinks, advection and aerosol interactions under a wide range of NH³ fluxes.
