- Abstract
-
Solar UV radiation reaching the Earth's surface is monitored by means of two
quantities: the clear-sky UV index at local solar noon and the daily UV
dose. Each quantity is determined on the basis of two action spectra,
describing wavelength dependent biological effects of UV radiation, namely
erythema (sunburn) and DNA-damage. The quantities are derived from total
ozone column measurements by the GOME and SCIAMACHY instruments, assimilated
into global ozone fields. For GOME a data archive has been set up spanning
the period August 1995 to May 2003. For SCIAMACHY a near-real time service
is in operation, which provides a forecast of the erythemal UV index for
today and a few days ahead, as well as yesterdays daily erythemal UV dose
for Europe (based on METEOSAT cloud cover data). A data archive spanning the
SCIAMACHY period will be set up. All data is available at the website of the
TEMIS project via http://www.temis.nl/uvradiation/

- Abstract
-
The L'Oréal group includes 17 global brands, some of which propose
lines of high-grade sunscreens. Research on the biological and chemical
effects of ultraviolet (UV) radiation on the skin and hair is of paramount
importance to assess the efficacy of cosmetic UV filters. UV irradiances and
daily doses are provided by the Tropospheric Emission Monitoring Internet
Service, which is managed by the National Dutch Meteorological Institute.
The data and the quality of service have been assessed. Comparisons with
available data, even if limited, showed excellent agreement. A few
requirements remain to be addressed, particularly data on UVA radiation.
They will be implemented within the existing user-friendly interface. All
these data will be used to improve the customization of sunscreens to
consumers' needs while answering health authorities' demands.
