Abstract

An evaluation was made from the results of four years of measurements of the CO2 exchange between grassland and the atmosphere. The measurements were performed at Cabauw, in the centre of the Netherlands. Data obtained during this project were made available to B.O.M. Dirks of Wageningen Agricultural University for validation of their "Grassland model". This work was funded by the Dutch ministry of Economic Affairs (contract nr 53476) with additional support for 1993 and 1994 from the National Research Programme on Global Air Pollution and Climatic Change (project nr 852076).
