The total solar radiation during the harmattan months of 1982 to the early part of 1984 at
Enugu, Nigeria, which lies on latitude 6.47° N and longitude 7.55° E and 140 m above sea …

The data on global irradiation incident on a horizontal surface in Port Harcourt during the 13-
year period 1977–1989 are analyzed and shown to vary with the climatic changes of the …

The global solar radiation in Awka, located at lat 6.20° N and long 7.12° E has been
measured using a Belfort actinograph on a continuous basis from November 1985 to May …

Diurnal global irradiation was measured with precision pyranometer in Nsukka, Nigeria and
compared with values generated from five different empirical models proposed by earlier …

Abstract Two Kipp and Zonen solarimeters, one of which incorporated a shadow ring, were
used for the measurement of the global and diffuse components of solar radiation for Kano …

Experimental work was carried out to determine the net flux of the long-wave radiation from
the earth's surface to the atmosphere for clear nights in Nsukka, Nigeria. Values of the …

Solar radiation equipment was found unreliable in the past, but presently is costly and not
readily available in developing countries. In such regions, use has to be made of models …

Results of spectral solar radiation measurements at Ile-Ife (7°-30′ N, 4° 31′ E; South
Western Nigeria) for two non-consecutive months between December 1991 and February …

An attempt has been made to correlate the total solar radiation with cloud cover and relative
sunshine duration for three Nigerian stations—Gusau, Potiskum and Yola. For Potiskum, an …
