Working group

Mohamed Saad, Nicolas Vuichard, Juliette Lathiere, Didier Hauglustaine

Planned work

1-Perform a set of simulations with the ORCHIDEE model to quantify the fluxes of nitrogen compounds (NH3,NOx,N2O) emitted by the soil.

2-Evaluate simulated emissions at national, continental and global scales by comparing them to emissions by other methods such as inventories (eg: EDGAR).

3-Develop the coupling between ORCHIDEE and INCA models in terms of downward (deposition)and upward(emissions) N fluxes.

Team meeting: 06/03/2019

Define the work steps:

• Read some bibliographical references related to the subject of work.
• Start by seeing outputs of a simulation performed by the ORCHIDEE model as part of NMIP (Tian et al., 2018a, b).
  • look at the variable NH3_EMISSION which gives the emissions per m2 of each type of vegetation. It is an information to combine with the file VEGET_MAX which gives us the fraction of mesh occupied by each type of vegetation.
• See the outputs of the NH3 simulations made by INCA to compare them with those of ORCHIDEE.

Team meeting: 13/03/2019

Evaluate the outputs of the NH3 (monthly, seasonal(averaged, maximum, minimum)) simulations of ORCHIDEE (2016) and INCA.
