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

In jpshanno/ecoflux: Functions for ecological flux studies including sap flux and soil/stem C efflux.

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.

Usage

pataki_flow(sap.flux, sapwood.area, diameter, tree.type)

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.

Examples

pataki_flow()
