The bulk transfer coefficients of momentum (C D ) and sensible heat (C H ) were determined from the field observation carried out on Nigerian Micrometeorological Experimental (Nimex_1) field, Ile-Ife, Nigeria. Direct determination of the transfer coefficients was done using the eddy correlation method. Analytical method was also used to compute the transfer coefficients with the use of bulk transfer algorithms. The C D and C H values obtained from eddy covariance method were higher than those from analytical method. Usage of the transfer coefficients obtained from analytical method will lead to slight underestimation of the fluxes. The atmospheric stability parameter z/L values were positive at nights (stability) but negative during the day (instability). The C D and C H values were higher during the day (instability) and lower at nights (stability). Whenever z/L was positive the sensible heat flux was negative.
