Dr Alessandro Anav University of Exeter

Research Project: Terrestrial ecosystem model evaluation ("TERREMIP")

Supervisor: Prof Pierre Friedlingstein (University of Exeter)
Secondary Supervisor: Dr Laurent Bopp (Commissariat a l'Energie Atomique)

T3.1 is a terrestrial ecosystem model evaluation project known as "TERREMIP". It will be a highly cross-cutting activity drawing on data and expertise from WP1, other WP3 tasks, and will utilise a common methodology developed in close collaboration with T2.1 ("MAREMIP"). Model evaluation will target the terrestrial components of models used by network partners and will exploit data from coupled GCM simulations submitted to the IPCC AR5 multi-model database.

Dr Daniela Dalmonech

Research Project: Benchmarking datasets for the evaluation of ecosystem models

Supervisor: Dr Sönke Zaehle (Max Planck Institute for Biogeochemistry)
Secondary Supervisors: Dr Laurent Bopp (Commissariat a l'Energie Atomique), Dr Filipe Aires (Estellus)

To develop a comprehensive series of benchmarks and associated methodologies for the systematic and quantitative evaluation of ESMs, with an emphasis on current regional and global biogeochemical cycles and their future behaviours. This task will be undertaken in close collaboration with the model comparison tasks T2.1 ('MAREMIP') and T3.1 ('TERREMIP'). Foci will be on the compilation and harmonisation of existing in situ measurements, inventories, atmospheric observations, and remote sensing datasets, and on developing evaluation techniques that move beyond simply testing models to the rigorous provision of constraints on future projections.

Research Project: Quantifying uncertainty in Earth system feedbacks to 2200

Supervisor: Dr Andrew Friend (University of Cambridge)
Secondary Supervisor: Dr Georg Feulner (Potsdam Institute for Climate Impact Research )

T5.1 will draw on all other network projects to develop and analyse an integrated framework for Earth system modelling, including socio-economic feedbacks. The SIMEARTH model platform will be used to develop a system of linkages and traceability across the hierarchy of GCII ESM components. SIMEARTH will be used to assess the consequences of different levels of complexity for model outcomes related to interactions between global biogeochemistry and climate.

Research Project: Marine ecosystem model evaluation ("MAREMIP")

Supervisor: Dr Laurent Bopp (Commissariat a l'Energie Atomique)
Secondary Supervisor: Dr Ute Schuster (University of Exeter)

T2.1 is a marine ecosystem model evaluation project known as "MAREMIP". It will be a highly cross-cutting activity drawing on data and expertise from WP1, model development from across WP2, and jointly derived methodology from WP3 ("TERREMIP"). The evaluation will build on previous model simulations and intercomparison projects such as OCMIP, C4MIP, FP6-Euroceans, and FP6-CARBOOCEAN, but also make use of the data available from coupled GCM simulations submitted to the IPCC AR5 multi-model database. The focus will be on developing evaluation techniques to move beyond simply evaluating models towards constraints on future projections.

Jorge Martinez-Rey LSCE

Research Project: Modelling the nitrogen cycle in the ocean

Supervisor: Dr Laurent Bopp (Commissariat a l'Energie Atomique)
Secondary Supervisor: Prof Nicolas Gruber (Eidgenössische Technische Hochschule Zürich)

Improve the representation of the marine N cycle in the PISCES ocean biogeochemical model. In particular, implementing a representation of the variability in phytoplankton N to C ratios and investigating how this may affect the response of air-sea C fluxes to climate change.

My research is focused on the current understanding of the marine N-cycle. The complexity of the N-cycle and its links with those of carbon and oxygen portray a beautiful yet challenging topic, from process parameterizations and OGCBMs to isotopic signatures and palaeorecords. Of particular interest in my work are the effects of future marine stressors such as global warming, ocean deoxygenation and ocean acidification on the marine N-cycle in the next hundred years.

The core of my work has been an improved representation of N-cycle processes in global ocean biogeochemical models, mostly on the in-house PISCES model at IPSL in France but also analysing the model output of the CMIP5 ensemble. The large uncertainties on the N-cycle demand not only to explore future projections on short time scales but also to identify the strengths and weaknesses of current OGCBMs in estimating critical processes such as N2O production, N2-fixation and nitrification under higher CO2 concentrations than today.
