Excel-based models that are useful in this class. These models are associated with various class exercises. You must download the XLSX file to perform the calculations.

  • Solar radiation incident on a surface (any slope angle, azimuth, time of day, or day of year)
  • Site water balance for any location in the Wasatch Mountains (monthly and annual)
  • Leaf temperature (any combination of climate and leaf coupling factors)
  • Photosynthetic rate of a C3 leaf (based on Farquhar models)
  • Canopy light penetration and photosynthesis (any distribution of leaf area and photosynthetic capacity)
  • Carbon isotope ratios of C3 and C4 plants
  • ​Plant growth
