Expertise and experience
The Max-Planck-Institute for Biogeochemistry (MPI-BGC) is a new research
institute of the German Max-Planck Society, founded in 1997. Its research
mission is the investigation of the global biogeochemical cycles and their
interaction with the climate system. The institute combines strong observational
and process-based studies (soil carbon, plant community structure, nutrition
and growth, vegetation-atmosphere fluxes, convective boundary layer) with
global scale modelling (e.g. vegetation dynamics, global carbon cycle,
aerosol modelling). The institute currently has a scientific and technical
staff of more than 100 people. Besides the renowned directors Profs. Schulze
and Heimann, a number of excellent and experienced scientists are working the
MPI-BGC on biogeochemical cycles at process-level (e.g., Dr. G. Gleixner),
site level (e.g., PD Dr. W. Kutsch), regional and global scale (e.g., Dr. C.
Gerbig, Dr. C. Roedenbeck, Dr. G. Churkina), providing an extraordinary
research environment for the proposed project. By 2006 three Independent
Junior Research Groups on vegetation and ecosystem modeling will have been
established, each one lead by Dr. C. Wirth (biodiversity and ecosystem
function), Dr. A. Kleidon (thermodynamic modelling), and Dr. M. Reichstein
(ecosystem model-data integration).
The MPI-BGC is one of the pivotal European biogeochemical cycle research
institutions, and as such is co-ordinating the EU-funded CARBOEUROPE-IP
project, and within the project the "Continental Integration" component.
Moreover the Institute is strongly involved in the recently EU-funded
NITROEUROPE project. The institute was involved in 12 of the 15 previous
CarboEurope projects, and co-ordinated three of them. MPI-BGC currently
hosts the European scientific office of CarboEurope and has proven skills
in co-ordination of international projects. MPI-BGC regularly advised
policy makers and has frequent contacts with media and the broad public.

Principal Investigator and collaborators
Markus Reichstein, PI, co-ordinator of WP3 is appointed as
Independent Junior Research Group Leader at the MPI-BGC. Graduated in
Landscape Ecology, University of Münster, Germany. PhD in Plant and
Ecosystem Ecology, University of Bayreuth, Germany, on the interpretation
and modeling of Mediterranean eddy covariance carbon and water fluxes in
response to drought. M.R. has then seen strongly involved in EU-Projects
VOCAMOD, MEDEFLU (FP4), CARBOEUROFLUX, MIND (FP5) and CARBOEUROPE-IP
Ecosystem and Integration components (FP6) and was modelling workpackage
coordinator of MIND. In 2004, he started the Intra-European Marie-Curie
project INTERMODE in the Department of Forest Ecology at the University
of Viterbo. Within these projects he developed expertise in the processing
and synthesis of eddy covariance carbon and water flux as well as soil
respiration data, robust ecosystem model-data integration techniques and
diagnostic ecosystem modeling using remote sensing information. In this
context he coordinated the ecosystem flux and remote sensing data
harmonization and interpretation for the analysis of the European 2003
heatwave (Ciais e al. 2005). Further, in co-operation with the University
of Montana and the PIK-Potsdam, the applicant is currently organising
the evaluation of global ecosystem productivity products coming from the
MODIS-satellite driven model and the dynamic LPJ model at European
flux-tower sites. This activity additionally is embedded into a broader
activity for the Global Terrestrial Observation System (GTOS) at the Food
and Agricultural Organization (FAO), where the candidate was appointed
to co-ordinate the 'Evaluation of Remote Sensing and In-situ Data Sets
for Carbon Accounting for the Ecosystem Productivity Project of GTOS'.
Werner Kutsch, Co-PI co-ordinator of WP2, is scientist at
the MPI-BGC. He was sub-project coordinator during the nationally funded
project 'Ecosystem Research in the Bornhöved Lake District' (1988-1999)
at the University of Kiel and PI of several research projects funded by
the DFG thereafter. From 2003 - 2004 he joined the international working
group running the flux tower Skukuza, South Africa and worked on eddy
covariance, leaf level gas exchange and soil respiration. At the MPI-BGI
he is now responsible for the flux towers of the Jena Cluster within
CarboEurope-IP. He is chair of the programme 'The Role of Soils in the
Terrestrial Carbon Balance' by the European Science Foundation.
Christian Beer, scientist, graduated in Mathematics and
Chemistry at the Friedrich Schiller University Jena, and obtained his
PhD in Geography with a thesis on linking and constraining soil and
vegetation process modelling with remote sensing in the EU funded project
Siberia II. He is a designated expert of the Dynamic Global Vegetation
model LPJ.
