Estimation of effective roughness length for heat and momentum from FIFE data

Abstract Using aircraft and surface data from the 1987 FIFE experiment in Kansas, we estimate the roughness length for momentum to be 0.19 m (with an error range 0.10–0.35 m), and the ratio of roughness length for momentum to that for heat to be about 16 (with an error range of 7–35).
