 == Last meeting ==
-=== On Wednesday, 19th October === 
 
-In person with Juliette, Didier and Nicolas. 
+=== On Wednesday, 2nd November === 
 
-Look on comparison of EDGAR inventory and the one of CEDS. Globally, their emissions are similar but if we look by sectors, there are different. In EDGAR, apparently, it could be better to drop fertilizers and biomass burning categories.
+Only with Nicolas.
 
-Use of NMVOC proxy: seems to be a good idea but have to drop some sectors already taken into account in orchidee dataset. NMVOC better than NH,,3,, because too related to agricultural sector, neither to CO because too related to industry, then NMVOC seem to be the less polluted by one particular sector.
+Mainly focusing on N,,2,,O reconstruction via proxy NMVOC. What I have done (using a increasing year per year ration for NMVOC and apply it on N,,2,,O data) doesn't give good results.
+
+New idea of using correlation between the two dataset, find the linear regression per region and use this equation to reconstruct N,,2,,O emissions. Seems better because the trend will be kept.
 
 __//**TO DO**//__
-   * Comparison of emissions (without soil emissions and fertilizers) and understood relationship between their subcategories;
-   * Have a look on geographical repartition (in order to see if patterns are similar);
-   * Proxy to recompute without soil emission and without domestic sector. (from 0 Tg/yr in 1750 to little in 1850);
-   * See with Anne to come into coupled model.
+   * Continue linear regression idea (avoiding negative values in the reconstruction and discontinuities in 1970);
+   * Prepare slides for ESM2025 meeting (4th of November).
 
-A few words on the next MERMAID meeting (December 14) with a presentation of N,,2,,O cycle and my work (introduction with Tian graph).
