28 Jun 2010 Global Warming Potentials (GWPs) are a quantified measure of the globally averaged atmosphere, and therefore have global average concentrations, are CO2, CH4, N2O, HFCs, PFCs, SF6 and NF3. Nitrous oxide (N2O).
Sensitivity of the boreal forest-mire ecotone CO2, CH4, and N2O global warming potential to rainy and dry weather. In a mosaic of well drained forests and poorly drained mires of boreal landscape the weather events such as drought and rainy control greenhouse gas dynamics and ecosystem global warming potential (GWP).

The GWP, however, re- duced to 91.73–211.80 Midseason aeration (MSA) is an effective way to reduce the combined global warming potential (GWP) of methane (CH4) and nitrous oxide (N2O) emissions 28 Mar 2019 The Global Warming Potential (GWP) for CO2 flux was 16105 kg CO2-eq ha-1, N2O 16403 kg CO2-eq ha-1.

De même, le N2O a un PRG 310 fois plus élevé que le dioxyde de carbone (GIEC, 20 Apr 2016 But the CO2, CH4, and N2O load is… carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) (I'm omitting halocarbons, which come COOLING DOWN GLOBAL WARMING.
On a time scale of 20-year period, the integrated global warming potential (GWP) of CH4 + N2O released during the rice growing season for the treatments of CF + RC, CF + WS and CF + CM was respectively 154%, 136% and 17% higher than that for the CF treatment, while a reduction of 10% was obtained for the CF + PM treatment.

Adviento-Borbe et al. (2007) pointed out that soil N 2 O emissions were a major contributor to the GWP in eastern Nebraska, USA. The total GWP of CH4 and N2O gases were decreased by 7-27 % and 6-34 % with calcium carbide, phosphogypsum, and silicate fertilizer amendments under continuous and intermittent irrigations, respectively.

In total GWP, about 96 % and 4 %, GHG was emitted as CH4 and N2O, respectively. The mean GWP of CH4 and N2O emissions from rice was 5758 kg CO2 eq ha⁻¹.

The GWP was a positive number, because the GWP from N 2 O emissions was significantly higher than that from CH 4 uptake . Therefore, direct N 2 O emissions dominated the GWP of the saline–alkaline systems in this study.
Mid-season drainage had no effect on rice grain yield. Although soil drainage times and organic matter amendment are important factors affecting CH4 and N2O emissions in rice paddy field, the study showed that neither of them had effect on the response of GWP to mid-season drainage.
