  We present the map of the artificial sky brightness in Europe in V band with
a resolution of approximately 1 km. The aim is to understand the state of night
sky pollution in Europe, to quantify the present situation and to allow future
monitoring of trends.
  The artificial sky brightness in each site at a given position on the sky is
obtained by integration of the contributions produced by every surface area in
the surroundings of the site. Each contribution is computed taking into account
based on detailed models the propagation in the atmosphere of the upward light
flux emitted by the area and measured by the Operational Linescan System of
DMSP satellites. The modelling technique, introduced and developed by Garstang
and also applied by Cinzano, takes into account the extinction along light
paths, a double scattering of light from atmospheric molecules and aerosols,
Earth curvature and allows to associate the predictions to the aerosol content
of the atmosphere.
