Provides parameter estimates based on both infinite and optimized mesophyll conductance, the late following Ethier and Livingston (2004). New version 11 December 2013.
Pressure/volume curvefitting based on the approach of Schulte and Hinckley (1985);Schulte,P. J., andT. M. Hinckley. 1985. A Comparison of Pressure-Volume Curve Data-Analysis Techniques. Journal of Experimental Botany 36:1590-1602. Now with uncertainty estimates 6 October 2008
Parameter estimates based on fitting a non-rectangular hyperbola following Marshall and Biscoe (1980) and Thornley and Johnson (1990).
Calculates bothType I and Type II regression intercepts. Provides objective criteria to guide removal of user-selectable outliers following Bowling et al. (2002).
Calculates leaf energy balance components (e.g. leaf temperature, transpiration, boundary-layer conductance, net radiation) from stomatal resistance, leaf size, shape, angle and solar radiation, windspeed, air temperature and relative humidity. Includes a worksheet for easy sensitivity analysis of different factors.
Calculates leaf transpiration from measurements of stomatal conductance (e.g. from a porometer). Required inputs are humidity, air temperature, leaf temperature and solar radiation at the leaf surface.
Includes both a standard 2-pool parallel 1st-order model and a reaction-progress variable or "curve-stripping" approach following Cerling et al. (2007).
Calculates uncertainty in source partitioning using stable isotopes for two-source mixing models, following Phillips and Gregg (2001).
The most common problem is getting the macro to run for the first time. If you are having this problem, its likely that the Solver function is not installed correctly...
