The results show that the sunny sunshine duration（SSD） has decreased significantly except at a few stations over northwestern China in the past 46 years. An obvious decrease of the SSD is found in eastern China, with the trend coefficients lower than-0.8. Accompanied by the SSD decline, the sunny diffuse radiation percentage（SDRP） in most stations shows obvious increasing trends during the 46 years. The averaged SDRP over China has increased 2.33%per decade, while the averaged SSD shows a decrease of-0.13 hr/day per decade. The correlation coefficient between SDRP and SSD is-0.88. SSD decreased over urban agglomerations（small to large city clusters） in the past 46 years, especially in large cities and medium cities, due to the strong anthropogenic activities and air pollution represented by aerosol option depth（AOD） and tropospheric column NO2（Tro NO2）. On the regional scale, SSD has an opposite trend from SDRP during 1960 to 2005, and the variation trends of regional mean values of SSD and SDRP in southeastern China are more pronounced than those in northwestern China.展开更多

Radiation cooling can achieve effective cooling without energy consumption by emitting heat into cold outer spacethrough an atmospheric transparent window (ATW, 8–13 lm)while reflecting solar irradiance in the solar region (0.3–2.5 lm)[1]. For example, Zeng et al. [2] reported a layered morphologyradiation-cooled textile composed of TiO2/polylactic acid and polytetrafluoroethylene. This design offers optimal mechanicalstrength, waterproofing and breathability, while enabling spectralmodulation within the 0.3–2.5 lm wavelength range and ensuringefficient radiative cooling. Yang et al. [3] developed a SiO2 microsphere-modified fabric film with shish-kebab structure. This fabricfilm exhibits high emissivity within the atmospheric window andstrong reflectivity to solar radiation, resulting in exceptional cooling properties for both indoor and outdoor applications. A key concern is that these radiation cooling textiles are typically appliedhorizontally, where they demonstrate effective cooling in sunny,unobstructed environments. However, their effectiveness may belimited in more complex real-world applications.展开更多
