A dynamic photosynthesis model

RuBP-regeneration parameter response to heat, water stress and light
 

Nicolas Bambach, myself and Kyaw Tha Paw U created a dynamic model of damage to photosynthesis that serves as an ‘add-on’ to the Farquhar-von Caemmerer-Berry model.  The model allows RuBP-regeneration limitation parameters to be damaged in response to extremes in leaf temperature, stomatal closure and limitations to photosynthesis and irradiance. Awesome!

The publication is:

This led to inclusion in an actual land surface model:

Nico’s work on dynamic damage to photosynthesis is calibrated with in situ fluorometers on almonds and allows for the interaction of environmental stress factors on the classical RuBP-regeneration parameters of photosynthesis
