Abstract Aerodynamic roughness length scale ( z 0 ) is an essential parameter for the parameterization of momentum flux exchanges at land-atmosphere interface. In this paper, several micrometeorological methods are applied for estimation of z 0 based on wind measurements at Hong Kong International Airport (HKIA). The concepts of source area and internal boundary layer are adopted to better understand the measurement results. The validity and prediction accuracy of the estimation methods for z 0 are examined and discussed. A map of terrain roughness at HKIA is established.
