英文摘要: Anthropogenic aerosols over urban areas may have important effects on surface incident solar radiation (Rs). Studies have claimed that Rs decreased significantly more in urban areas than in rural areas from 1964 to 1989. However, these estimates have substantial biases because they ignored the spatial inhomogeneity of Rs measurements. To address this issue, we selected urban-rural station pairs collocated within 2° × 2° and found 105 such pairs based on the Global Energy Balance Archive (GEBA). On average, the impact of urban aerosols on mean and trend of Rs is 0.2(0.7, median) ± 11.2 W m-2 and 0.1(-0.7, median) ± 6.6 W m-2 per decade from 1961 to 1990, respectively. Hence, the averaged urban impacts on the mean and trend of Rs over Europe, China and Japan from 1961 to 1990 are small although they may be significant at specific sites. Key Points Urbanization has small impacts on mean and trend of surface solar radiation Our estimates are based on urban-rural stations pairs Previous estimates include substantial spatial biases ©2014.
