Internship of Louis-Axel Edouard-Rambaut
This internship has been conducted during my Master 1 of Ecology. 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.
I - N2O emissions
A - Emissions of N2O in ORCHIDEE
1 - Maps of emissions for the 2010-2015 period
Figure 1 : Emissions of N2O (in gN2O-N.m-2.an-1) estimated by ORCHIDEE for the 2010-2015 period for all the PFTs
B - Effects of the fertilizers on the emissions
Global annual emissions of N2O (in TgN.an-1) estimated by ORCHIDEE in fonction of the fertilizers (in TgN.an-1). In blue i represented the linear regresssion and the grey zone correspond to the confidence intreval of the regression.
2 - Evolution of the emissions for the 1861-2016 period
Figure 3 : Emissions of N2O (in gN2O-N.m-2.an-1) estimated by ORCHIDEE for the 1860-2015 period for the whole world
In black is represented the emissions for all the PFTs.
In blue is represented the emissions for the PFTs 12 and 13.
In green is represented the emissions for the PFTs 10, 11, 12 and 13.
In orange is represented the emissions for the PFTs 1 to 9
B - EDGAR and ORCHIDEE
PFT selected in ORCHIDEE : 10 ; 11 ; 12 ; 13 (only of the N_Fertilizants there was striclty positive)
Sources of emissions selected in EDGAR (http://edgar.jrc.ec.europa.eu/overview.php?v=432_GHG&SECURE=123) :
- Agricultural soils (4C + 4D) [AS]
- Indirect N2O emissions from agriculture (4D3) [I]
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.
Grid resolution :
- ORCHIDEE : 0.5°*0.5°
- EDGAR : 0.1°*0.1°
Period studied :
- ORCHIDEE : from 01/01/1861 to 31/12/2016, monthly emissions
- EDGAR : from 1970 to 2012, annual emissions
C - Comparaison of N2O emissions between EDGAR and ORCHIDEE
Means emissions estimated of N2O for each region for differents regions by EDGAR and ORCHIDEE for the period 1970-1975 (in Tg N2O-N.an-1). The Standard-Deviation are represented by the variation bar. The regions of temperate Asia, tropical Asia, north America and south America are nammed withe following terms «ATemp», «ATrop», «AN», «AS».
Means emissions estimated of N2O for each region for differents regions by EDGAR and ORCHIDEE for the period 2007-2012 (in Tg N2O-N.an-1). The Standard-Deviation are represented by the variation bar. The regions of temperate Asia, tropical Asia, north America and south America are nammed withe following terms «ATemp», «ATrop», «AN», «AS».
Emissions of N2O (en gN.m-2.an-1) to the global scale by EDGAR (a) and by ORCHIDEE (b)
