Historical Ultraviolet Index (UVI)

National Environment Agency (NEA) archives historical Ultraviolet Index (UVI) readings for Singapore from 2016 through 2024 in annual CSV files. Timestamps use Singapore Time in ISO 8601, consistent with other NEA historical forecast collections. Public health researchers and outdoor activity planners should note NEA’s disclaimer on data gaps and non-climate quality control. For certified climatology, contact [email protected]; this series suits analysis of UV exposure trends from operational forecast archives.

Historical Ultraviolet Index (UVI) (2023)

Historical Ultraviolet Index (UVI) data for Singapore covering 2023. The dataset supports research and reference on ultraviolet radiation conditions over time, with timestamps provided in Singapore Time (SGT) using ISO 8601 formatting. Its geographic scope is Singapore, while the available time dimension is limited to the historical records represented for 2023; the dataset description does not specify a finer spatial breakdown or observation frequency. It may be relevant for searches and analyses involving Singapore UV conditions, seasonal or date-based UVI review, environmental monitoring, UV exposure studies, climate and weather research, and the planning or evaluation of public-facing UV information. Users should account for potentially missing records and note that the data has not undergone the quality-control procedures applied to official climate data and records. For authoritative climate records or prepared climate data reports, contact the National Environment Agency at [email protected]; fees may apply.
