A brief account is given of on‐going measurements of solar and long‐wave radiation fluxes over Ile‐Ife (7.29°N, 4.34°E), Nigeria. Pyrheliometric measurements of direct solar radiation using an Ångström compensation Pyrheliometer were initially made over the 1984/85, 1985/86, and 1986/87 harmattan seasons. Then followed the establishment, in 1992, of a solar radiation monitoring station, capable of carrying out continuous measurement of global and diffuse solar radiation using Kipp and Zonen pyranometers, along with the long‐wave (sky) radiation using a pyrgeometer and, the photometric flux, using a LICOR LI‐210SA photometric sensor. Spectral measurements of solar radiation made over 300–1100 nm region using a LICOR LI‐1800 spectroradiometer of 6 nm resolution are discussed along with the relevant applications. The measurement efforts constitute a step towards the building up of a climatological data bank capable of meeting solar energy utilization demands as well as providing inputs for Climate and planetary boundary layer models and satellite remote sensing applications.
