GROUP and Objectives

• Implicated persons : Nathalies DN, Devaraju N., Philippe C., Philippe P., Nicolas Vuichard, Natasha MacB, Sebastiaan, Sushi P., ...

• Projects : CMIP6, ECVLCOVER, LUC4C and ERACLIM2 at least.

• Objectives / roadmap : Prepare the land cover map changes with the 13 PFTs for the past (back to 1500) and for the future (CMIP6 scenarios), using ECV-lcover product for current Land Cover and CMIP6 rules for natural vs anthropic changes provided by G. Hurtt.

• Main "developers" : Devaraju will do the year to year reconstructions from G. Hurtt products; Natasha will provide from ECVlcover project the current land Cover map for ORCHIDEE PFTs; Other will contribute scientifically.

Meeting of the 17 September

• Persons: Nathalie, Devaraju, Natasha, Catherine, Nicolas, Philippe

• Objectives: discussion on how to use the CMIP6 land use information data provided by G. Hurtt (natural vs managed) and the recent ECV-lcover land cover map to derive yearly ORCHIDEE PFT maps for past and futur simulations

• A summary is provided in summary meeting​

• Actions:

Devaraju will reconstruct the PFT historical maps using the ECV-lcover map and G. Hurtt historical data. First comparison of GH map for the year 2000 with the ECVlcover map has been derived by Dev comparison GH versus ECVlcover​

We need to gather in order to possibly revise the cross walking table that allows to convert the FAO land cover classes into ORCHIDEE PFT fractions
