摘      要：Two models based on Li et al. (2011) are developed for general application in estimating the monthly average daily diffuse solar radiation in China. The validation of these models is performed by comparing with four existing empirical models against the measured data. It is found that the proposed models have better performance than these existing models. This study further argues that ambient temperature and relative humidity incorporated into empirical models can generally improve its estimates. Hence, the two models can be recommended for general application in estimating the monthly average daily diffuse solar radiation in China. (C) 2012 Elsevier Ltd. All rights reserved.
