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.
