NCI precipitation effects

Precipitation effects adjust tree growth based on plot precipitation.


Weibull precipitation effect

Parameters

Weibull Precip Effect "A" The A parameter for the precipitation effect. Units of precipitation are millimeters per year.
Weibull Precip Effect "B" The B parameter for the precipitation effect. Units of precipitation are millimeters per year.
Weibull Precip Effect "C" The C parameter for the precipitation effect. Units of precipitation are millimeters per year.

How it works

Precipitation Effect is calculated as:

PE = Weibull climate growth precipitation effect equation
