Data and Software

Data products, online services and open software

Below, find a couple of published and unpublished tools, services and data products from the Department of Biogeochemical Integration. These tools are available online or upon request from the respective contact person. These products are free for non-commercial use if not mentioned otherwise. For data products we only ask for personal contact (an automatic registration is on the way) to be able to track use of the data, and provide updates and further information via a e-mail to users.

Data sets

In general, BGI data products are available from our data portal	http://www.bgc-jena.mpg.de/geodb/BGI/Home In case of problems please contact:	Fabian Gans, Miguel Mahecha
Site level estimates of GPP and TER from FLUXNET eddy covariance stations	This data set is derived from the LaThuile-2007-FLUXNET data set as documented at according to the new algorithm by Lasslop et al. (2010). Site data is freely available after authorization by the respective site PI.	Gitta Lasslop, Markus Reichstein
