NCI nitrogen effects

Note: If these effects are used with NCI Mortality, the time period unit for parameters must match the value specified in the NCI Parameter Period (years) parameter.

Gaussian nitrogen effect

Parameters

Nitrogen Effect X0	The X₀ parameter for the nitrogen effect.
Nitrogen Effect X0	The X_b parameter for the nitrogen effect.

How it works

Nitrogen Effect is calculated as:

where:

X₀ is the Nitrogen Effect X0 parameter
X_b is the Nitrogen Effect Xb parameter
N is the plot's annual nitrogen deposition value, as entered for the Plot
