pataki_flow: Calculate sap flow for a tree with sapwood depth greater than...

Description Usage Arguments Value Examples

Description

This function uses the equations laid out in Pataki et al, 2011 to calculate the total sap flow of a tree from sap flux measurements in the outer sapwood. It assumes a 2 cm long sap-flux probe and silently considers the total stem area to be sapwood area if the sapwood area is greater than the area of the tree caluclated form the diameter argument.

Arguments

sap.flux

Sap flux data as volume per unit area per unit time

sapwood.area

Sapwood area of the tree in units matching sap.flux area unit

diameter

Diameter of the tree in units matching the square root of the sap.flux area unit

tree.type

is a character of 'Softwood' or 'Hardwood'

Value

Sap flow of the stem given as volume per unit time matching the units in sap.flux.
