摘要
地表太阳辐射(SSR)是实现公平和可持续未来的基本能源。气象引起的变异性增加了 SSR 的不确定性,从而因其间歇性而限制了其可靠性。这种可变性取决于多种气象因素,包括云、大气气体和气溶胶浓度。本研究调查了不同程度的云和气溶胶对印度各地 SSR 的详细影响。研究利用卫星数据和再分析检索,涵盖了从 1993 年到 2022 年的三十年(30 年)时间跨度。气溶胶对 SSR 的平均衰减率约为 13.33%,而高云、中云和低云条件的影响更大,衰减率分别约为 30.80%、40.10% 和 44.30%。该研究揭示了近十年来云层对 SSR 的影响(Cimpact)不断增加的惊人模式,高云(HCimpact)和中云(MCimpact)的影响分别以 ~0.22% 和 ~0.13% 的年增长率显著增加,而低云影响(LCimpact)则变化甚微。气溶胶影响(Aimpact)的趋势也显示,所有地区平均每年增加约 0.14%。这些发现强调,在研究日趋严重的太阳暗化现象时,必须考虑气候变量。我们的研究结果还将帮助决策者和规划者更好地评估印度各地的太阳能资源。
Spatiotemporal Assessment of Surface Solar Dimming in India: Impacts of Multi-Level Clouds and Atmospheric Aerosols
Surface solar radiation (SSR) is a fundamental energy source for an equitable and sustainable future. Meteorology-induced variability increases uncertainty in SSR, thereby limiting its reliability due to its intermittent nature. This variability depends on several meteorological factors, including clouds, atmospheric gases, and aerosol concentrations. This research investigates the detailed impact of different levels of clouds and aerosols on SSR across India. Utilizing satellite data with reanalysis retrievals, the research covers a span of three decades (30 years), from 1993 to 2022. Aerosols contributed to an average attenuation of ~13.33% on SSR, while high, mid, and low cloud conditions showed much stronger impacts, with an attenuation of ~30.80%, ~40.10%, and ~44.30%, respectively. This study reveals an alarming pattern of increasing cloud impact (Cimpact) on SSR in the recent decade, with a significant increasing rate of ~0.22% year−1 for high cloud (HCimpact) and ~0.13% year−1 for mid cloud (MCimpact) impact, while low cloud impact (LCimpact) showed minimal change. The trend of aerosol impact (Aimpact) also showed an average increase of ~0.14% year−1 across all regions. The findings underscore the imperative of considering climatic variables while studying the growing solar dimming. Our findings also will assist policymakers and planners in better evaluating the solar energy resources across India.
