v21 v22 4 4 5 5 This internship has been conducted during my Master 1 of Ecology. 6 This work comports N parts, the first correspond to the work done for the intership report on the comparaison of the N2O emissions ine ORCHIDEE with the same emission in the EDGAR inventories. The second part correspond to the additional work i did with the same compariason of emission this time done on the NH3 emissions. 6 This work is a first report of the global emissions of N2O and NH3 estimated by the model. 7 The localisation of the main emission, the evolution of the emissions and the response of the emissions with fertilizers have been described. The emissions estimated in ORCHIDEE have been compared with the one estimated by the inventory EDGAR. A work of hgarmonization have been conducted to allow a robust comparaison between the EDGAR sources and ORCHIDEE. 7 8 8 9 [https://forge.ipsl.jussieu.fr/orchidee/attachment/wiki/DevelopmentActivities/ORCHIDEE-CN/stage_edouard-rambaut/Rapport%20Louis-Axel.pdf Internship_report.pdf] … … 18 19 [https://vesg.ipsl.upmc.fr/thredds/catalog/store/p529vui/OL2/PROD/NMIP-halfdeg/catalog.html] : 19 20 20 21 For EDGAR we selected several Sources of emissions selected:21 To compare the emissions estimated in ORCHIDEE and in EDGAR, we only took agricultural soils emissions. 22 For EDGAR we selected several Sources of emissions : 22 23 * Agricultural soils (4C + 4D) [AS] 23 24 * Indirect N2O emissions from agriculture (4D3) [I] 24 25 25 The total emissions of N2O we took in consideration is T = [AS] - [I] since the leaching flux are put out of the system in ORCHIDEE. 26 The total emissions of N2O we took in consideration is T = [AS] - [I] since the leaching flux are put out of the system in ORCHIDEE. 26 27 27 28 The emissions relatives to those sources are obtainable here in EDGAR ([http://edgar.jrc.ec.europa.eu/overview.php?v=432_GHG&SECURE=123]) 29 30 31 We compared these emissions estimated by EDGAR with the emissions of the PFTs 10, 11, 12 and 13. 32 28 33 29 34 Grid resolution :
