Abstract:
The aim of the title project was quantification of the reduction of solarradiation by anthropogenic aerosol in Europe by a combination of approaches.
These complementary approaches were: (1) Assessment of the optical properties
of the European aerosol; (2) Trend analysis of solar radiation and
anthropogenic aerosol loadings; and (3) Modeling of the effect of aerosol on
local radiation/climate, using parametrized aerosol, and comparison of the
parametrized aerosol with measured aerosol data in Europe. The tasks of ECN
were the following: Coordination of the project and editing of the final
report (ECN-C-95-030): ad (1) Assessment of the light-scattering properties
of the aerosol in Western Europe, combined with solar radiation measurements;
ad (2) Analysis of the trend in aerosol loading in Europe; and ad (3)
Measurement of aerosol size/composition. With respect to task 1, the
investigation by ECN was subdivided into: the evaluation of existing data,
and performing of new measurements, including assessment of the humidity
dependence of the light-scattering. In this report only those aspects which
have not been published before in reports and publications on the project
subject are described in detail. For the subjects published earlier only the
key elements are given. Additional details can be found in the ECN-reports of
which the numbers are given at the end of the respective chapters. The
results and conclusions of the various tasks/chapters were integrated into
those of the final report (ECN-C-95-030). 16 figs., 3 tabs., 21 refs.
