Abstract

Sky condition evaluation in north-east geo-political zone of Nigeria has been carried out in this paper. Twenty years (2000-2020) data of daily global solar radiation and monthly average bright sunshine hours are sourced from National Aeronautics and Space Administration (NASA) and Nigeria Meteorological Agency (NIMET), respectively. The zone consists of six states. Total average global solar radiation on horizontal surface of 69.05 kWhrm-2day-1 is estimated for the zone. Monthly average clearness index ranges from 0.42 – 0.69. These depict that cloudy sky condition is prevalent in north-east of Nigeria. A monthly bright sunshine hour of the geo-political zone is estimated at 94.16 hrs. Five (5) seasonal classification periods are recorded in Bauchi, Damaturu and Yola. In Gombe and Maidugri, six seasonal classification periods were observed. While in Jalingo, seven seasonal periods were identified. Coefficients of determination are estimated for Angstrom-Page equation for the study locations and zone.
