【 摘 要 】

The estimation of the solar radiation at Uturu latitude 05.33oN and 06.03oN was carried out in this work. The temperature data were obtained from 5th – 31st October, 2007) using the maximum and minimum thermometer placed in the Stevenson screen at 1.5 m The Hargreaves equation was used to estimate the solar radiation at Uturu. The mean global solar radiation obtained for the period is 1.89±0.82kwh per day. A comparison of the mean solar radiation result obtained at Uturu and that obtained by Chineke (2007) at Umudike (5o29’N, 7o33’E) in October, 1997 and Chineke (2002) at Owerri (5o28’N, 7o2’E) in October, 1997 showed that the solar radiation obtained at Uturu is low. This difference may be attributed to the fact that Uturu is bounded on the West and South by a hilly escarpment.
