Recalculation Values
Parameter
Description
LAR
Leaf Area.
PAR
PAR. This is typically ghosted out and should only be
available when using our “Manual” style cuvettes and
PAR was manually entered and not measured.
RB
Boundary Layer resistance of Cuvette. The value
depends upon the type of cuvette supplied. The
factory default value can be found on the cuvette
handle or packing list supplied with the system.
TRANS
The transmission characteristics of the cuvette
window. This value is different for each type of
cuvette and is automatically set by the CIRAS-2 by
default when selected in the Parameters Editor dialog.
This value should not require changing.
RSFract
The ratio of stomata on the upper and lower surface
of the leaf. Please note that the ratio is in terms of
the upper leaf. During recalculation, the value should
be entered as a percentage of 1 (i.e. 50% Stomata on
top surface should be entered as 0.50).
Flow
Flow rate of the integral air supply. If the CIRAS-2 air
supply is used, there should be no need to change
this value. If an external air supply is used, this value
may require changing.
Leaf Temp.
Leaf Temperature. If set to Energy Balance, leaf
temperature is automatically recalculated. If set to
Use Existing, recalculation does not occur.
