Objective
a) To study the clear-sky and cloudy-sky UV trends.
b) To study the relative importance of various factors on UV irradiance at ground level.
c) To improve the parametrisation of radiative transfer models as based on UV and ancillary measurements.
d) To develop UV-B scenarios for Europe as based on ozone scenarios taking into account increase of atmospheric CO2 concentration.
The UVRAPPF project contains following research tasks:
1. Past changes in solar UV-B radiation in Northern Europe
2. Processes affecting UV-B radiation in Northern Europe
3. Parametrisation of radiative transfer models
4. Development of UV-B scenarios
The first task will be realised by using up to 20 year time-series of quality-controlled broadband UV-B
measurements, up to 45 years of total ozone measurements, other radiation measurements and radiative transfer
models. Special emphasis has been paid on the quality control of UV records at the stations selected for the
UVRAPPF project.
The second task will be realised by studying several years of routine, quality-controlled spectral UV
measurements performed at 8 stations in Northern Europe. The vertical distribution of ozone, aerosols and
meteorological parameters, records of total O3, SO2 and NO2, measurements of solar radiation, clouds and
albedo, performed for several years at the stations will be used for studying the effect of various factors in
affecting UV-B irradiance. These processes will be partly studied with DISORT and UVSPEC radiative transfer
models. The results of these studies will further be used for improving the parametrisation on the radiative
transfer models.
Finally, UV-B scenarios for the next century for Europe will be produced by using the newest stratospheric
ozone scenarios, as produced by the leading stratospheric
chemistry/dynamics modelling groups. Of special
interest will be to model the effect of CO2 increase on Arctic polar vortex and further to ozone, together with
the existing halogenated compound scenarios.
