UV-Check



The UV-Check Service provides local and indivialized near-real-time sunburn times, UV-Indices, and sun protection factor recommendations via Short Message Service (SMS) and internet web-page.
Visitors of the sites www.uv-check.com (in English) or www.uv-check.de (in German) can easily and without charge register themselves and/or their family members by creating individual profiles containing name, age, and skin type. To account for the high temporal and spatial variations of clouds or surface conditions as for example snow cover, reflecting water surfaces, or small scale terrain structures, the UV-Check enables the user himself to enter this information. The service products are provided for locations, i.e. cities, towns, villages, requested and specified by the user within the area of Europe. For selected regions in the Mediterranean area the similar MEDSUN service is specifically devised. Currently UV-Check accounts for the variability of total ozone in time and space by using data from the GOME-2 (Global Ozone Monitoring Experiment-2) instrument operating aboard the European MetOp satellite as input.

Latest results

Currently sunburn times are shown that are based on climatological total ozone values derived from ERS-2/GOME data. Maps illustrate the short sunburn times in July due to high UV intensity under clear sky conditions. Note, burntimes will be further reduced in case of snow cover, especially in the mountains. Burntimes will be prolonged when the sun is obscured by clouds.

Sunburn time on 01. September
Sunburn time on 15. September
Sunburn time on 31. September

UV-Check results as well as related total ozone column amounts for the years 2006 and 2007 covering the area of Europe are archived offline. Contact Ralf Meerkötter (below).

Validation of the UV-algorithm, examples and related publications

The erythemal UV calculated by the central UV-algorithm of the UV-Check service has been compared to surface measurements in several studies. The erythemal UV is the basic quantity from which UV-Check products as sunburn time and UV-Index are derived.
