I have plenty of data from leaves, but is there a way to calculate their photosynthesis rate?

I count with:

• Leaf temperature
• Leaf VPD
• Stomatal conductance and density (stomata/cm2) and their % aperture
• RH & Temperature from the environment
• Irradiation from the sun (W/m2)
• PAR Light

I know that the best way to obtain photosynthesis rate is with a enclosed chamber and measure the decrease of CO2, but is there a way to calculate it with some of the data that I already have?

I have been searching for a mathematical model or any kind of coupled equations, but I haven't found any info.

Thanks in advance.
