Detailed Description

Calculates ETpot after Oudin et al 2005.

https://doi.org/10.1016/j.jhydrol.2004.08.026 This ETpot formula is a generalization of two older approaches by introducing parameters to shape the dependency of ETpot from temperature and extraterrestrial radiation

\( \lambda ET_{pot} = R_{a} \cdot \frac{T_{a} + K_2}{K_1}\)

Oudin et al (2005) found an optimum for \(K_1=100, K_2=5\). The origin of this formula lays in Jensen & Haise (1963) with \(K_1=40, K_2=0\) and McGuiness-Bordne (1972) with \(K_1=68, K_2=5\).

Public Member Functions
real	conc (cmf::math::Time t, const cmf::water::solute &_Solute)
	Returns the concentration of the flux.
flux_node::ptr	get_target (const flux_node &inquirer)
	Returns the other end of a connection than the asking end.
flux_node::ptr	get_target (int index) const
	With index 0, the left node is returned, with index 1 the right node of the connection.
real	get_tracer_filter ()
	A value ranging from 0 to 1 to filter tracers out of the water flux.
real	get_tracer_filter (solute S)
	A value ranging from 0 to 1 to filter tracers out of the water flux.
bool	kill_me ()
	Deregisters this connection from its nodes. Returns true if only one reference is left.
flux_node::ptr	left_node () const
	Returns the left node of this connection.
real	q (const flux_node &inquirer, cmf::math::Time t)
	Returns the current flux through a connection. Negative signs mean out of the inquirer, positive are inflows to the inquirer.
void	refresh (cmf::math::Time t)
	Performes a new calculation of the flux.
flux_node::ptr	right_node () const
	returns the right node of this connection
void	set_tracer_filter (real value)
	A value ranging from 0 to 1 to filter tracers out of the water flux.

Static Public Member Functions
static void	use_for_cell (cmf::upslope::Cell &cell)
	Connects all soil layers with the transpiration node of the cell.

Public Attributes
const std::string	type
	A string describing the type of the connection.

Member Function Documentation

conc()

real conc ( cmf::math::Time t, const cmf::water::solute & _Solute )

inherited

Returns the concentration of the flux.

If not overridden, it returns the concentration of the source of the flux (direction depending)

get_tracer_filter()

real get_tracer_filter ( )

inherited

A value ranging from 0 to 1 to filter tracers out of the water flux.

1.0 is no filter and 0.0 means no solute is crossing this connection

set_tracer_filter()

void set_tracer_filter ( real value )

inherited

A value ranging from 0 to 1 to filter tracers out of the water flux.

1.0 is no filter and 0.0 means no solute is crossing this connection
