The innovative sampling design was home-built for the study, enabling accurate ecosystem-scale measurements of emissions via fast response and low losses. A high flow (5000 litres per minute) through the chimney inlet enabled sampling of the sticky highly reactive organic compounds without any inlet wall losses. A 3-D sonic anemometer is mounted above the inlet to measure wind speed in all 3 directions enabling the researchers to do eddy covariance. The state-of-the-art Vocus proton transfer mass spectrometer is in a weather-proof, air-conditioned box.
