A series of the daily averaged net all‐wave radiative flux measurements recorded at a tropical location in West Africa (Osu, Nigeria; 7ċ43°N, 4ċ58°E) for the period 31, December 1994 to 19, December 1995 is presented in this study. The preliminary data set showed the annual trend as bimodal, with peak values of about 140 W m −2 day −1 in March and November, and a prominent minima of about 70 W m −2 ; day −1 in August, which is at the peak of the monsoon season. The mean for the year was 103ċ65±30ċ13 W m −2 day −1 . Day‐to‐day fluctuations of the daily averages increased markedly during the wet season (which is from April to October). The annual pattern is also investigated by the Fourier series expansion method. ©1997 by the Royal Meteorological Society. Int. J.
