Name Prequel Underlying data Unit Range No data Description
Foliage height FOLIAGE_HEIGHT Heat Prequel m 0 to 100 Clamped to range Used for initializing the relative foliage heights.



Notes

  • Warning: The wind factor reduction is very susceptible to variation in foliage heights, leading to significant higher PET values in forested areas. It is advised that this prequel is smoothed with max and average techniques.
  • The values in this prequel grid are clamped between 0m and 100m. No data values are not allowed, although negative no data values will result in a foliage height of 0.
  • The foliage height is a relative height value in meters. Not the datum height.
