RESEARCH, DRIVING GROWTH
Motivation for participating in the project
Hair and skin occupy a special place
on the surface of the human body, in
direct contact with the environment.
Their diversity and the alterations
they may show are partly linked to
climate and pollution.
Exposure to solar radiation can have severe
The UltraViolet waveband of the solar spectrum
is involved in these alterations.
UV irradiances and doses
Both physical (UVB, UVA) and biologically-weigthed (erythemal)
Kind of data:
- Global and local maxima and averages
- Time series at different locations
Too few (or geographically missing) collecting sites
Limited availability of data over time
Instrumental intercomparison is required because of
- calibration and operating procedures
No data on UVA radiation available
« Physical » requirements:
- Sea level
- Region: Global, but focused on populated areas
- Spatial resolution: 1 by 1 degree
- Time period: climatology
- Max. time delay: means for every ten days or less/more often depending on
the variation in time of the product (a significant variation is 20 %)
- (When applicable: Spectral step: 1 nm)
- Accuracy: better than 5%
- Improvement proposals
- Related links
Clear-sky UV index, global and Europe
Erythemal UV doses:
Comparisons with published models and local ground measures
Ease of use / care of specifications
- full answer
EXPECTATIONS FOR THE REMAINDER
IN THE PROJECT
- Interactive maps
- UV-index and UV doses results after may 2003 (i.e. based on SCIAMACHY):
Yearly averages and extrema, monthly averages and climatologies, both for
global and areas of interest
Improve the relevance of indoor tests:
to consumer needs, worldwide
