Relations between net radiation, global solar radiation, and sunshine on the north coast of New South Wales

Key Points

• The study aims to predict net radiation based on global solar radiation and atmospheric conditions.
• Data collected at Wollongbar on the north coast of New South Wales.
• Daily measurements of global solar radiation were used for predictions.
• Extraterrestrial radiation values were tabulated and included in analyses.
• Atmospheric transmissivity term was incorporated into the relation.
• Developed relation predicts net radiation (Qn) with high accuracy.
• The model explained 85% of the variation in net radiation with the inclusion of the atmospheric term.
• Without the atmospheric transmissivity term, the explained variation was only 79%.
