Study of the Relative Change of Reflected Radiation in the City of Basra

Abstract

Studying the subject of the study Studying the study of inverse change in the city of Basra "The study came to clarify the concept and characteristics of solar radiation and then reveal the factors affecting radiation in the study of the characteristics of the study of solar radiation, radiation angles to the surface of the earth, theoretical and actual brightness, then a beautiful location and water vapor pressure to reach To know the variation of the areas of reflected radiation and its relative change in the city of Basra and for the period (1988-2020). The study reached a number of results, including:

The study revealed that the highest values of total solar radiation were recorded in the months (May, June, July, August) as they amounted to (648.52, 697.2, 709.59, 673.94) megajoules / m2 day in Basra station.

The lowest values of the reflected radiation at the Basra station were during the months of (June, July and August), as its values were (147.0, 151.9, 148.8) megajoules/m2 day at the Basra station.

The study found that the values of relative change varied during the study period in Basra station, as it reached its highest value in August (9.05), while the lowest value was recorded in April (7.70), and in May it reached (7.75) for Basra station.
