[[PageOutline]]

This page is dedicated to the ESM2025 project (Earth System Models - European Project), especially for the N-cycle modelling.
On this topic are working Marion Gehlen, Juliette Lathière, Didier Hauglustaine, Nicolas Vuichard and Karine Laurent.

== Work in Progress ==

=== On Wednesday, 20th April === 

=== On Wednesday, 6th April === 

In Visio with Nicolas, Juliette, Didier, Marion.

Mainly, this meeting was to talk a bit more about the project and the work I(=Karine) can make before the training session (April 14th & 15th).

Discussion on:
* the first result made with INCAFLX and 3 different inventories,
* the planning we can set up (which kind of simulation...)
* the impact of N2O on chemistry (if everything is coupled), 
* the certainty (or uncertainty) of inventories used (to determine an appropriate scaling), 
* the work of Pierre for aquatic emissions (importance of river emissions),

//Planning :// Run simulation without chemistry and no rescaling, first for pre-industrial, then until now to see/understand the correction we can make on both period (a different correction for each period).

=> This have to be detailed and confirmed

Maybe run only 10 years to know where are sinks, determine some lifetime/seasonal cycle in order to calculate the scaling we may use.

Suggestions to work with the GES branch for the code (branch for coupled model with CO2, CH4 and N2O)

**Meeting every 2 weeks same day, same time (ie, Wednesday at 10:00)**


__//**To DO**//__
* Ask for writing a Wiki page on IGCMG 
* Log on JupyterHub
* Make an "experiment plan" for future simulations
* Analyse the results that I've already (seasonal analyses, comparison between inventories with Bouwman as a reference, recap origin/grid resolution...)
* Show the aquatic variable of Bouwman (and maybe some others)

Didier : emissions file for pre-industrial fires to be send to Karine
