Full Harvard record provides a range of realistic PAR values Calculating J using Jmax from Griffen pers comm and J = (jmax +PhiPAR - sqrt((jmax+PhiPAR)^2-4thetajmaxPhiPAR))/2*theta

Canopy light study from Harvard Forest (David Foster)
Driving equation 1(a) Results in the following J calculations
This is summarized here:
Most of the time ... it's dark
if you think about it isotopically ... most of the signal should be made up from periods when photosynthesis is actually happening ... at really low light, the overall isotopic signal is probably not being changed. I'll need to think about how to deal with this
Calculate the stomatal limitation for photosynthesis for each canopy position light level
