Lab: Modelling the photosynthetic response to environmental conditions

10:00 am - 12:00 pm, 17th July, 2019 (T2)

In this lab we are going to explore the C3 leaf-level photosynthesis model proposed by Farquhar et al. (1980) and use this to simulate photosynthesis at leaf, ecosystem and global scale

We are going to use this model to:

• learn how leaf-level photosynthesis responds to changes in the environmental forcing (photosynthetically active radiation, temperature and carbon dioxide).
• simulate GPP at the ecosystem-scale (~1 km^2) using FLUXNET (eddy covariance) meteorological data.
• simulate a global estimate of GPP.

Running on your own computer

To run the practical:

1. Download or clone the entire repository, either:
   • Download the repository as a zip file, and uncompress it.
   • git clone https://github.com/mdekauwe/CLIM3001_lab_photosynthesis.git
2. Then open up the project file in the repository folder in RStudio.
3. You will have to knit the Rmd file to generate the practical instructions. To do so, open the Rmd file and click the knit icon.
