DISCLAIMER       /      FOREST SITE DE INSLAG, BRASSCHAAT, Belgium

USE OF METEOROLOGICAL and EDDY FLUX DATA 

General:
The meteorological data of the state forest De Inslag (Brasschaat, Belgium) on this CD have been processed from data kindly provided by the Institute for Forestry and Game Management (IFG, Geraardsbergen, Belgium). The eddy covariance data of the state forest De Inslag (Brasschaat, Belgium) on this CD have been processed from data collected by the Department of Biology, Research Group of Plant and Vegetation Ecology of the University of Antwerpen (UIA, Wilrijk, Belgium).

All data were checked, filled to provide complete records, and processed into a consistent format. This is the first release of the data, but the data are subject to change. Users are urged  to communicate with the Institute for Forestry and Game Management and/or the University of Antwerpen, UIA, and are reminded that data, when used for publication, are subject to IFG fair use rules.

Fair Use Policy:
Kindly keep us informed of how you are using our data and of any publication plans.  If we feel that we should be acknowledged or offered participation as authors, we will let you know and we assume that an agreement on such matters will be reached prior to publishing the data.  If your work directly competes with our analysis we may ask that we have the opportunity to submit a manuscript before you submit one that uses our data. Anyone planning to publish or use meteorological data should both notify the Institute for Forestry and Game Management and cite the below-listed reports and papers describing the data collection methodology. Anyone planning to publish or use the eddy covariance flux data should both notify the Research Group of Plant and Vegetation Ecology, Department of Biology, University of Antwerpen, UIA, and cite the below-listed references describing the data collection methodology and first analysis.
