%X Data collected at several observation sites of HEIFE were used to estimate local roughness length for momentum. Combining of remote sensing data, an experienced formula for calculating roughness length for momentum was obtained from normalized difference vegetation index I NDV .Further, area roughness length for momentum for summer and early winter were estimated by this relationship, which was validated by measurements in the field.
