Mối quan hệ giữa bức xạ mặt trời và số giờ nắng tại Việt Nam (tiếng Anh). TS. Nguyễn Thế Bảo. Renewable Energy Vol. 11, năm 1997.
Astract: Two approaches of the well-known modified Angstrom formula were developed from long term records of measured monthly mean daily global solar radiation and sunshine hour values obtained from 12 meteorological stations across Vietnam. These formulae were then used to estimate solar radiation for stations where only sunshine records were available. Three other commonly used correlations between solar irradiation and sunshineduration were also used and their results compared with those of two developed models. The procedure of measurement in Vietnamese weather stations was also indicated.
