v45 v46 3 3 [[PageOutline]] 4 4 5 5 This internship has been made for the validation of my Chemistry License 3. [[BR]] 6 6 This has been done with rev 4164. My work is divided in 4 parts, the first part corresponds to the work done for the internship report. Then, the second part is a brief bibliography about emission factors. Then, the third part corresponds to the second part of my internship: analyzing ammonia emission factor. Finally, the last part corresponds to a brief look at a global simulation of the model made by P.Messina.[[BR]] 7 7 8 8 9 == I.

This equilibrium explains the influence of the different pools on NH3 emissions. Also, pH takes an important role in this reaction. [[BR]] 89 The comparison with LMDz-INCA model's data shows us that the results we obtained with ORCHIDEE model are in the good order of magnitude, but also that those datasets are hardly comparable because they don't take in count the same sources. The data we obtained with ORCHIDEE model doesn't contain emissions due to fertilization. [[BR]] 90 That is why we have to make simulation with fertilization in the first place and then a global simulation in order to see if ammonia emission have the same behavior concerning the influence of the parameters we studied. 91 88 92 ---- 89 93 … … 99 103 ---- 100 104 101 == III.
