This paper describes a procedure that can be used to calculate values for Linke atmospheric turbidity factors at air mass 2 (TL2) over Zimbabwe. Ground measured daily global solar radiation on clear days over 3years is used to evaluate TL2 for those stations that measure global radiation. The...

Measurements of different components of solar radiation were carried out in Helwan, Cairo, Egypt. Helwan (Lat. 29° 52′ N, Long. 31° 20′ E) is considered the largest polluted region in the world and, the sources of pollution are cement, engineering, iron and steel factories. The data...

The scarcity of hourly solar radiation data for locations in Vietnam presents difficulties in using simulation packages for assessing the potential of solar energy systems in that country. This paper describes a computer model to generate daily and hourly solar radiation sequences from monthly...
