Urban Aerodynamic Roughness Length Mapping Using Multitemporal SAR Data

<div>The backscattering coefficient extracted from various upwind sectors for the Beijing meteorological tower. (a) is the ALOS PALSAR image on 21 June 2007, and (b)–(d) show the backscattering coefficient within the predefined upwind sector with a radius of 4500 m, opening angles of 30°, 45°, and 60°, respectively.</div>
