Resumen:
Assessment of the air quality in metropolitan areas is a major challenge
in environmental sciences. Issues related include the distribution of
monitoring stations, their spatial range, or missing information. In
Mexico City, stations have been located spanning the entire Metropolitan
zone for pollutants, such as CO, NO2, O-3, SO2, PM2.5, PM10, NO, NOx,
and PMCO. A fundamental question is whether the number and location of
such stations are adequate to optimally cover the city. By analyzing
spatio-temporal correlations for pollutant measurements, we evaluated
the distribution and performance of monitoring stations in Mexico City
from 2009 to 2018. Based on our analysis, air quality evaluation of
those contaminants is adequate to cover the 16 boroughs of Mexico City,
with the exception of SO2, since its spatial range is shorter than the
one needed to cover the whole surface of the city. We observed that NO
and NOx concentrations must be taken into account since their long-range
dispersion may have relevant consequences for public health. With this
approach, we may be able to propose policy based on systematic criteria
to locate new monitoring stations.
