Abstract

In this study, the usability of clear sky radiation and Angstrom coefficients depend on geographical and meteorological parameters for predicting monthly mean global solar radiation in Bishkek, Kyrgyzstan were investigated. A multiple linear regression was applied to explain the relationship among Angstrom coefficients and geographical and meteorological data sets which were monthly mean clear sky or extraterrestrial radiation, the ratio of sunshine hours to day length, ambient and soil temperatures, relative humidity, sine of declination angle. Variables in these equations were used to estimate the global solar radiation. Values calculated from models were compared with the meteorological values.

Özet

Bu çalışmada, Bişkek, Kırgızistan’da coğrafik ve meteorolojik parametrelere bağlı olarak Angstrom katsayısı ve açık gökyüzü ışımasının kullanılabilirliği araştırıldı. Aylık ortalama açık gökyüzü ışıması veya atmosfer dışı ışıma, güneşlenme süresinin gün uzunluğuna oranı, çevre ve toprak sıcaklıkları, bağıl nem, deklinasyon açısı gibi meteorolojik parametreler ve Angstrom katsayıları arasındaki ilişkiyi açıklamak için çok yönlü lineer regresyon uygulandı. Daha sonra bu eşitliklerdeki değişkenler toplam güneş ışımasını hesaplamada kullanıldı. Modellerden hesaplanan değerler meteorolojik değerlerle mukayese edildi.
