Abstract: A ground-based eddy flux system which is used to measure the CO2 and H2O exchange between the atmosphere and the biosphere is described. Fluctuations of CO2, H2O, air temperature and atmospheric turbulence are sampled at ...

Abstract: A spatial network of 25 air temperature sensors was deployed over an area of 3.5 km ? 3.5 km of agricultural land, aiming to calculate the sensible heat flux by spatial averaging instead of temporal averaging. Since ...

Abstract: The partial solar eclipse on 11 July 1991 in central California, with 58.3% maximum coverage, provided an exceptional opportunity to study the temporal response of processes in the atmospheric boundary layer to an abrupt ...

Abstract: Daytime isoprene emissions were measured over a black spruce forest in Saskatchewan (Canada) during the Boreal Ecosystem Atmosphere Study of 1994. The relaxed eddy-accumulation (REA) technique was used to measure isoprene ...

Abstract: Repeated aircraft runs at about 33 m over heterogeneous terrain are analyzed to study the spatial variability of the mesoscale flow and turbulent fluxes. An irrigated area, about 12 km across, generates a relatively cool ...
