Abstract

Solar radiation data is important parameter to estimate
solar energy which is a major renewable energy in terms of sustainable
resources. Accurate spatial and temporal distribution of solar radiation is
required not only to estimate solar energy but also hydrological,
meteorological and climatological studies. General objective of the study is to
examine accuracy of freely available Climate Forecast System Reanalysis (CFSR)
solar radiation data against ground observation data based on monthly and
yearly averages over the Hatay province in Turkey. The CFSR dataset including
25 daily solar radiation measurement points was evaluated against 12 ground
stations for 21-year period (1985 - 2006). Statistical results showed that most
correlations in monthly basis data were weakly correlated except October (R2=0.73).
According to results of Bias, CFSR monthly averaged solar energy was over
estimated for all months. Also, CFSR annual solar energy 28% higher than ground-based
observed solar energy with R2=0.76. Annual CFSR solar energy found
between 5.2 and 5.6 kWh m-2day-1.
Annual ground-based solar energy ranged from 3.9 to 4.2 kWh m-2day-1.
The result showed that, it is unacceptable to use the CFSR dataset in case of
lack of measured values of ground-based solar radiation in monthly and yearly
averaged basis. Estimated CFSR data has need to be improved and accuracy of
CFSR data must be tested for other regions in Turkey. We recommend finding
another source of satellite-based data to compare with ground-based data.

Abstract

Solar radyasyon verileri,
sürdürülebilir kaynaklar açısından önemli bir yenilenebilir enerji olan güneş
enerjisini tahmin etmek için önemli bir parametredir.
Solar radyasyonun
alansal ve zamansal dağılım doğruluğu sadece güneş enerjisi tahmini için değil
ayrıca hidrolojik, meteorolojik ve iklimsel çalışmalar için de gereklidir.
Çalışmanın genel amacı,
Türkiye'nin Hatay ili üzerinde ki aylık ve yıllık ortalamalara dayanan yer
gözlem verilerine karşı ücretsiz olarak elde edilebilen CFSR solar radyasyon
verilerinin doğruluğunu incelemektir.

21 yıllık dönem için 25 adet günlük solar radyasyon ölçüm noktaları içeren CFSR veri seti, 12
yer istasyonuna karşı değerlendirilmiştir (1985- 2006).
İstatistiksel sonuçlar, aylık bazda ki
verilerin çoğunun Ekim ayı dışında aralarında zayıf ilişki olduğunu
göstermiştir (R2 = 0.73).

Bias sonuçlarına göre,
CFSR aylık ortalama güneş enerjisi tüm aylar için tahmin edilmiştir.
Ayrıca, CFSR yıllık güneş enerjisi R2
= 0.76 ile yer esaslı gözlemlenen güneş enerjisinden %28 daha yüksek olduğu
belirlenmiştir.
Yıllık CFSR güneş
enerjisi, 5.2 ile 5.6 kWh m-2gün-1 arasında bulunmuştur.
Yıllık yer esaslı güneş enerjisi ise
3,9 ile 4,2 kWh m-2gün-1 arasında değişmektedir.
Sonuçlar, aylık ve yıllık ortalama
olarak ölçülen yer esaslı solar radyasyon değerleri bulunmaması durumunda, CFSR
veri setinin kullanılmasının kabul edilemez olduğunu göstermiştir.
CFSR verilerinin iyileştirilmesine
ihtiyaç olduğu ve Türkiye'de diğer bölgeler için CFSR verilerinin doğruluğu
test edilmesinin gerekli olduğu tahmin edilmiştir.
Yere esaslı verilerle karşılaştırmak
için başka bir uydu tabanlı veri kaynağı bulunmasını önermekteyiz.
