The Air Resources Laboratory (ARL), conducts research on processes that relate
to air quality and climate,
concentrating on the transport, dispersion, transformation, and removal of trace gases and aerosols,
their climatic and ecological influences, and exchange between the atmosphere and biological and
non-biological surfaces. The time frame of interest ranges from minutes and hours to that of the
global climate. Research in all of these areas involves physical and numerical studies, leading to
the development of air quality simulation models. ARL provides scientific and technical advice to
elements of NOAA and other Government agencies on atmospheric science, environmental problems,
emergency assistance (Homeland Security), and climate change.
