ESM2025-N-cycle

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.

Meeting Reports

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
