Units
User entered displacement height; 0 for
m
auto calculation
Displacement height used in
calculations; it will equal
m displacement_user if user entered a
non-zero value; if displacement_user is
zero, program will auto calculate
Roughness length entered by user (if
m left as 0, the program autocalculates a
value)
Roughness length; if roughness_user =
0, z0 is determined by the program; if
m
roughness_user ≠ 0, z0 is set to
roughness_user.
m Aerodynamic height
m Monin-Obukhov length
