UVdose: an R package for estimating ambient vitamin D-effective UVB and erythemal UV doses.

Ultraviolet (UV) radiation plays a critical role in both beneficial and harmful health outcomes, such as vitamin D synthesis or skin erythema. Accurate quantification of UV exposure relevant to health outcomes is essential in epidemiological and clinical research. We present UVdose, an R package designed to estimate biologically relevant UV doses, including vitamin D-effective UVB and erythemal UV, using the gridded UV products from the Thematic Emission Monitoring Integrated Services (TEMIS) database. The package provides user-friendly tools for integrating environmental UV exposure data, enabling reproducible and scalable analyses in population health and clinical studies.
