Περίληψη:
The strong economic growth in China in recent decades, together with
meteorological factors, has resulted in serious air pollution problems,
in particular over large industrialized areas with high population
density. To reduce the concentrations of pollutants, air pollution
control policies have been successfully implemented, resulting in the
gradual decrease of air pollution in China during the last decade, as
evidenced from both satellite and ground-based measurements. The aims of
the Dragon 4 project “Air quality over China” were the determination
of trends in the concentrations of aerosols and trace gases,
quantification of emissions using a top-down approach and gain a better
understanding of the sources, transport and underlying processes
contributing to air pollution. This was achieved through (a) satellite
observations of trace gases and aerosols to study the temporal and
spatial variability of air pollutants; (b) derivation of trace gas
emissions from satellite observations to study sources of air pollution
and improve air quality modeling; and (c) study effects of haze on air
quality. In these studies, the satellite observations are complemented
with ground-based observations and modeling.
