Solar UV-A radiation causes photocarcinogenesis and skin photoageing, but it could also benefit cardiovascular health and protection from autoimmunity.

In this study, a method for the near real-time monitoring of UV-A solar radiation dose based on Earth Observation satellites imagery is proposed. The calculated satellite-derived radiant dose has been compared to ground measurements provided by Public Health England solar monitoring network at eight locations in the UK and Republic of Ireland in April–October 2015. The statistical analysis showed a good correlation between satellite-derived exposure doses and direct ground measurements under all weather conditions, significantly improved for clear skies. The proposed method may be considered for the integration into digital mobile apps for healthcare, assisting users to balance risks and benefits of sun exposure in an accessible way.

太阳UV-A辐射会引起光致癌作用和皮肤光老化，但也可能有益于心血管健康并保护自身免疫。

本文提出了一种基于地球观测卫星图像的紫外线-A太阳辐射剂量近实时监测方法。已将计算得出的卫星辐射剂量与英国公共卫生太阳能监测网络在2015年4月至10月在英国和爱尔兰共和国的八个地点提供的地面测量结果进行了比较。统计分析表明，卫星辐射剂量之间存在良好的相关性并在所有天气条件下进行直接地面测量，对于晴朗的天空而言，显着改善。可以考虑将所建议的方法集成到医疗保健的数字移动应用程序中，以帮助用户以可访问的方式平衡暴露于阳光下的风险和收益。
