The amount of canopy coverage changed between 19.6% and 45.2%.
The algorithm outputs are the average temperature of sunlit leaves and canopy coverage.
Structural plans were modelled t in three stages; increased building height, adding tree canopy coverage and adding green roofs.
Tree canopy coverage tends to increase with sensitivity in Portland, while the reverse relationship is found for Phoenix.
Urban variables for design are trees canopy coverage area ratio, traffic load, walls surfaces albedo, and H/W.
The model combines four stand structure parameters: canopy coverage, age of canopy trees, tree species composition and canopy stratification.
We also measured the percentage of herbaceous vegetation (grass, forbs, and total herbaceous vegetation) canopy coverage using 20 × 50-cm Daubenmire plots (Daubenmire 1959).
At the nest site (i.e., 15-m spatial scale), we measured shrub canopy and sagebrush canopy coverage using line intercept methods (Canfield 1941).
Urban variables studied are: the extent of tree canopy coverage, traffic load, surfaces albedo modification, street deepening aspect and the street's ventilation.
The case study is a street in Athens with low aspect ratio H/W (H: building height; W: street width), low trees canopy coverage level, and high traffic.
