Description | ||||||
In this paper, models are developed with regression equations to predict the solar ultraviolet radiation (Iuv) based on measured sun position values for Lashio, in Northern Shan state, Myanmar. These measurements are taken daily in an equinox. The value of the mean bias error (MBE), mean square error (RMSE) and mean percentage error root (MPE) were determined for the equation. The values of the correlation coefficient (r) and coefficient of determination (R2) were also determined for each equation. The equation with the highest values of r, R2 and at least values of RMSE, MBE and MPE is given as Iuv = 22.49 e-0.0152 θz – 6.321 named as a natural exponent model where θz is solar zenith angle. The results obtained show a remarkable agreement between the measured and the predicted values using our proposed models. | ||||||
