  "definition": "The aerodynamic roughness length, a parameter representing the effective height above the ground where the mean wind speed becomes theoretically zero due to surface friction. It quantifies the roughness of a surface and its impact on atmospheric flow. Typical values range from fractions of a millimeter over smooth ice to several meters over dense urban areas.",
