monitor-to-monitor temporal correlation of air pollution and weather variables in the north-central u.s. - outdoor monitor

Many time series studies have reported an association between daily environmental concentrations of air pollution and morbidity or mortality.
Recent personal exposure studies have also reported a relatively high longitudinal correlation between individual exposure to particulate matter (PM)
And home Outdoor PM concentrations, which provide support for the health effects reported in Time Series studies.
However, the problem remains, how the time fluctuation of air pollution levels observed on outdoor monitors represents the time fluctuation of exposure of urban outdoor source contaminated population, and how this representation affects the scale and significance of risk estimates.
Also, such time and space
Temporal correlations vary from pollutant to pollutant and may affect their relative importance to the statistical association of health outcomes.
In this study, we describe the scope of monitoringto-
