Foliage height calculation model
Notes
- The decline of the foliage height cannot be changed, it will always be linear.
- As noted above, the vegetation fraction and Bowen ratio are also changed when the foliage height is set to a positive height. This means it is also set when a GeoTIFF or areas are used to set the foliage height.
- Warning: The wind factor reduction is very susceptible to variation in foliage heights, leading to significantly higher PET values in forested areas. It is advised that this prequel is smoothed with an average setup with the max method for rasterization. The original DPRA Heat stress report uses relatively large foliage areas as input.
