Popis:	Carbon dioxide and water vapour flux measurements made above a Danish coniferous/hardwoods stand were compared with the environmental parameters air temperature and global radiation. We show consecutive measurements from April 1995 to August 1996. The fluxes are determined by micrometeorological gradient methods using a 36 m mast. For 1995 and 1996 the following general patterns is seen: From spring to July the cumulative CO2 flux from the forest ecosystem is building up biomass (1.05 kg CO2 m−2). From August on, the system starts loosing carbon (0.9 kg CO2 m−2).
