Regional carbon budgets: limitations and improvements of the top-down and
bottom-up approaches.
Chair: Martin Heimann
Following up on the modeling and data analysis work performed in the continental integration
component, the double session addresses the limitations and progress of the different
approaches in establishing regional carbon budgets on seasonal, annual, interannual and
pentadal time scales. The session includes the following topics by means of short
presentations and general discussions:
Bottom-up approaches:
− climate driver data
− land use, land cover and land management history
− bottom-up model simulation intercomparisons
− inventory based estimates
Top-down approaches:
− biosphere experiment
− signals of the fossil fuel CO2 emissions
− top-down inversion synthesis
“Minor” fluxes (carbon trade products, erosion, rivers, coastal ocean, non-CO2 reduced
carbon compounds)
Top-down vs bottom-up synthesis
We have already several solicited presentations, but additional contributions are welcome.

How far is the carbon sink stimulated by N-deposition?
Contributers: A. Freibauer, F Magnani, S Luyssaert, M Sutton
In the last few months, three independent reviews show that the forest carbon sink is strongly
dependent on atmospheric deposition of nitrogen. However, the studies differ in their
quantitative prediction. The purpose of the session is to bring together the authors of these
studies to explore the reasons for the discrepancy and to suggest processes and mechanisms which need to be better understood before we can make predictions of what will happen over
the next century.
Questions to be addressed:
− How tightly are C and N tranformations in soil and ecosystems coupled?
− How do ecosystems respond to increased N input?
− Can N be used as a further constraint to C sequestration and the C budget? How much
is ecosystem response to more favourable climate conditions and CO2 limited by N?
− Are past and new results on forest response to N consistent?
Major products will be:
− Synthesis on C-N interactions in forests, hopefully also other ecosystems and soils
− Priorities for future research on the C-N linkage
The session will also link to NitroEurope.

| Advection (ppt-file, 8.578 kb)
Chair: Christian Feigenwinter
The session will address the latest findings in the analysis of the ADVEX campaigns in
Renon, Wetzstein and Norunda. We are additionally interested in other ADVEX-site specific
contributions, e.g. addressing NEE, NEP, TER, soil efflux, footprint problems, model
simulations, turbulence characteristics, etc. Of course also non ADVEX-site related
contributions about advection are especially welcome. The final discussion will address the
direction of future ADVEX related scientific work with the long-term objective of developing
a robust correction scheme for EC fluxes.

Processes driving GPP, NPP and NBP
Chair: Philippe Ciais
Pursuing initial synthesis work initiated by the 'process task force', this session will address
quantitative estimates of GPP, NPP, NBP and of their driving processes, using data and
models at continental and regional scales. The session will examine the limitations and
advantages of diverse approaches (models, eddy data upscaling, forest biomass inventories...).
The session will consist of short presentations and general discussions |
Flux data synthesis (ppt-file, 1.322 kb)
Conveners: Markus Reichstein, Dario Papale, Riccardo Valentini
The ecosystem parallel session will report on progress regarding ecosystem-scale
observations in CarboEurope that might include
− Synthesis of carbon water and energy flux data, vegetation biometric data and soil
information (e.g. summaries of climate, landuse, management influences),
− Ecosystem physiological insights,
− Analyses of seasonal and interannual variability,
− Model evaluations,
− Measurement uncertainty aspects and
− Novel analytical methods to investigate temporal/spatial variability |

The accumulation of biomass-carbon in forest ecosystems- data that challenge
our models
Contributers: E-D Schulze, J Grace, S Luyssaert, G-J Nabuurs, N Viovy, F Magnani
Ecosystem models are general conceived as 'point' models and are rarely applied in a way that
enables management practices to be explored. Yet European forests are nearly all managed,
and much of the forest carbon sink is thought to be the result of a management regime that
keeps the forest in a productive stage of its growth. How far can forest models be used to
simulate the age-related and management-related process at the large scale? If they can, we
may be able to answer policy-related 'what if' questions at the European scale and therefore
substantially extend and intensify the carbon sink. |

CarboSchools is an initiative which promotes partnerships between global change scientists,
secondary school teachers and their students in order to raise young people's awareness of the
local and global consequences of climate change, to encourage them to discover the scientific
research and to act locally to reduce emissions of greenhouse gases. CarboSchools is
proposed by two large European research projects on climate change, CarboEurope and
CarboOcean, in which more than 100 institutes from 17 countries are working together to
investigate the carbon cycle on land and ocean respectively.

Uncertainties in measuring and modelling carbon and greenhouse gas
balances in Europe (ppt-file, 2.696 kb)
Chair: Martin Wattenbach
The first half of the session will be talks where the second part will focus on the discussion of
the uncertainty protocol drafted by the JUTF (Joint Uncertainty Task Force of Carbo- and
Nitro-Europe). Topics in the focus of the talks and the discussion are:
− temporal uncertainties in measured data e.g. gap filling procedures, u* correction,
filtering etc.
− spatial uncertainties e.g. representativeness of sample points, interpolation and
extrapolation methods, geo- statistics
− uncertainties in temporal and spatial scaling approaches
− uncertainty in model applications at the site scale
− uncertainty in model based up-scaling approaches
− way to reduce uncertainty in models e.g. Bayesian approaches, Pareto and others
− ways to identify and reduce uncertainties in measurements
