|Characterisation Method Name:|
|N2O impact on base cat-ion capacity|
|Principal Method Name:|
|EPS: NOx-tranformation pathway|
|Model for NOx-tranformation pathway|
The characterisation factor is determined by an equivalency method using NOx as a reference.
In "N2O impact on YOLL" the equivalency factor was determined to 1.35 kg NOx (NO2).
The characterisation factor of NOx for base cat ion capacity is determined in "NOx impact on base cat-ion capacity" to 1.09 equivalents of base cat-ions per kg NOx. Therefore the characterisation factor of
N2O for soil base-cat-ions is 1.35*1.09 = 1.47 equivalents of base cat-ions /kg N2O.

|The impact is of global character. The modelled system is therefore global. The temporal system borders are 100 years (1990-2090). The society effected is the one described in IPCC scenario IS92A. (IPCC, 1990).|
