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

Variations in the average monthly, seasonal and daily patterns of total radiation, relative
humidity, temperature and sunshine duration in Ibadan have been presented. Various …

Sunshine duration hours, minimum and maximum daily temperatures, relative humidity,
mean daily temperatures and specific humidity, all as monthly averages for a 60-month time …

An empirical correlation for estimating monthly mean daily total solar radiation on a
horizontal surface is suggested from latitude, altitude, sunshine duration, monthly mean …

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 …

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 …

An attempt has been made to correlate the total solar radiation for Yola and Calabar with
available meteorological data on sunshine duration, maximum air temperature and relative …

In this paper, monthly mean surface data of solar radiation and air temperature for the period
1970-1995 were obtained from the archives of the Nigerian Meteorological Agency (NIMET) …

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 …

Solar energy is one of the most promising renewable sources. It is environmentally friendly,
plentiful and easy to utilize. Energy plays a pivotal role in socio-economic development by …
