Resource title Net Ecosystem Exchange chamber measurements of CO2 and latent heat fluxes at the edge effect site
Resource abstract Manual measurements with a tunnel-shaped flow-through chamber (covered surface area: approx. 1.6 m²) of CO2 and latent heat fluxes at the edge effect site, at several IOPs near the start of the campaign. Land use types: Wheat/fodder field (Eddy Covariance reference data available), grassland ("), poorly drained grassland spot (no reference fluxes), maize (no reference fluxes).

Quality and validity
Process history and quality information Raw measurements of CO2 and H2O concentration in chamber in- and outlet, wind speed in outlet, temperature and pressure in gas analyzer => block-averaged (10-30 min) fluxes of CO2 and H2O per unit time and ground surface area.
