NCI temperature effects

Temperature effects adjust tree growth based on mean annual temperature.

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.


Weibull temperature effect

Parameters

Weibull Temperature Effect "A"The A parameter for the temperature effect. The effect is based on mean annual temperature in degrees Celsius.
Weibull Temperature Effect "B" The B parameter for the temperature effect. The effect is based on mean annual temperature in degrees Celsius.
Weibull Temperature Effect "C" The C parameter for the temperature effect. The effect is based on mean annual temperature in degrees Celsius.

How it works

Temperature Effect is calculated as:

TE = Weibull climate growth temperature effect equation

where:


Double logistic temperature effect

Parameters

Double Logistic Temp Effect "al"The al parameter for the temperature effect. The effect is based on mean annual temperature in degrees Kelvin.
Double Logistic Temp Effect "bl"The bl parameter for the temperature effect. The effect is based on mean annual temperature in degrees Kelvin.
Double Logistic Temp Effect "cl"The cl parameter for the temperature effect. The effect is based on mean annual temperature in degrees Kelvin.
Double Logistic Temp Effect "ah"The ah parameter for the temperature effect. The effect is based on mean annual temperature in degrees Kelvin.
Double Logistic Temp Effect "bh"The bh parameter for the temperature effect. The effect is based on mean annual temperature in degrees Kelvin.
Double Logistic Temp Effect "ch"The ch parameter for the temperature effect. The effect is based on mean annual temperature in degrees Kelvin.
