| 英文摘要 | Solar radiation is the principal and fundamental energy for many physical, chemical, and biological processes. Estimation of solar radiation from sunshine duration is common employed when no direct observation of solar radiation is available. Particularly, the Angstrom-Prescott (A-P) model is widely used for its simplicity. This paper investigates the effect of time scale on the A-P parameters and the estimation accuracy using the data of 13 sites in Northeastern China. The results show that the A-P model can not be applied at annual, but less than seasonal time scale. Time scale effects the spatial variation of a and b parameters of the calibration curve, it has greater effect on parameter a than on b; while greater effect on temporal variation of b than that of a, and the differences of the parameters caused by time scales are generally large, however, the large differences of parameters do not result in significant difference of the estimation accuracy. Therefore, parameters at different time scales are interchangeable, the parameters calibrated at larger time scales can be applied to smaller time scales, and vice versa. |
