A simplified method for infrared and ultraviolet solar radiation analysis in Riyadh, Saudi Arabia

Abstract

The present work describes a simplified method for field data which include total, direct, infrared (IR) and ultraviolet (UV) solar radiation in Riyadh for the period from 1982 to 1992. Four dimensionless parameters namely A A1,B and B are considered to study the d' d daily, monthly and yearly variations. Two normalized parameters for UV and IR are also introduced The observed variations in UV and IR together with their implicit and normalized parameters enable us to a better understanding of some environmental effects in the region such as UV/IR scattering, UV/IR reflection, clouds, ozone, and temperature.
