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.

You will find information on the evolution of the project on these different pages:

On Wednesday, 24th August

In person with Didier and Nicolas. PDF support (see attached file ).

Resume of august simulations and work.

• Transformation of CEDS emissions: from 1970 to 1999, use of netCDF file 2000 with a factor per sector to create netcdf emissions. Notebooks Transform_2000nc_from1970_to1999_via_CEDScsv.ipynb and work_on_data_to_complete_sectors_with_unknows_categories.ipynb
• 2 simulations: L39.v03 as a base (pre-industrial, constrained to 285ppm), then pi_piscideeL (free, pre industrial, 40 years).

Results seem good regarding vertical pressure profile, total loss N₂O, pattern of emissions. Need to investigate more and continue.

TO DO

• Make graph of pressure for those two simulations,
• Continue piscideeL 5 years and compute mean of loss,
• Resume differences between former simulations,
• Re-create netCDF files with only manure_management (and not soil_emissions) for agricultural sector.

Intermediate conclusions: some partial conclusions;

Intermediate Conclusions

Pre industrial run

• 39 layers,
• from fictives years 1970 to 2015

• Total N₂O loss: 10.73 TgN/y
• Total N₂O emissions: 10.73 TgN/y
• Burden : 1368 TgN

CEDS emissions for N₂O (and NH₃)

Notebooks list

5. work_on_data_to_complete_sectors_with_unknows_categories : Notebook in order to better understand repartition of subcategories that are not in CEDS emissions files and grouped in sectors.
6. Transform_2000nc_from1970_to1999_via_CEDScsv : To reconstruct geographical emissions from 1970 to 1999 from 2000's emissions and with a ratio computed thanks to csv's data. Need to use obelix' script home/users/klaurent/CEDS_transform/nco_transform_1970_1999_ncfiles.sh after this notebook (delete _FillValue mainly).

References: some interesting references (to do).
