MILAGRO (Megacity Initiative: Local And
Global Research Observations) is an international
collaborative project to examine the behavior and the export of atmospheric
emissions from a megacity. The Mexico City Metropolitan Area (MCMA) – one
of the world's largest megacities and North America's most populous city –
was selected as the case study to characterize the sources, concentrations,
transport, and transformation processes of the gases and fine particles emitted to the
MCMA atmosphere and to evaluate the regional and global impacts of these
emissions. The findings of this study are relevant to the evolution and
impacts of pollution from many other megacities.
The measurement phase consisted of a month-long series of carefully
coordinated observations of the chemistry and physics of the atmosphere in
and near Mexico City during March 2006, using a wide range of instruments at
ground sites, on aircraft and satellites, and enlisting over 450 scientists
from 150 institutions in 30 countries. Three ground supersites were set up
to examine the evolution of the primary emitted gases and fine particles.
Additional platforms in or near Mexico City included mobile vans containing
scientific laboratories and mobile and stationary upward-looking lidars.
Seven instrumented research aircraft provided information about the
atmosphere over a large region and at various altitudes. Satellite-based
instruments peered down into the atmosphere, providing even larger
geographical coverage. The overall campaign was complemented by
meteorological forecasting and numerical simulations, satellite observations
and surface networks. Together, these research observations have provided
the most comprehensive characterization of the MCMA's urban and regional
atmospheric composition and chemistry that will take years to analyze and
evaluate fully.
In this paper we review over 120 papers resulting from the MILAGRO/INTEX-B
Campaign that have been published or submitted, as well as relevant papers
from the earlier MCMA-2003 Campaign, with the aim of providing a road map
for the scientific community interested in understanding the emissions from
a megacity such as the MCMA and their impacts on air quality and climate.
This paper describes the measurements performed during MILAGRO and the
results obtained on MCMA's atmospheric meteorology and dynamics, emissions
of gases and fine particles, sources and concentrations of volatile organic
compounds, urban and regional photochemistry, ambient particulate matter,
aerosol radiative properties, urban plume characterization, and health
studies. A summary of key findings from the field study is presented. |
