Description:
This paper presents an assessment of the temporal and spatial behavior of measured ozone concentrations over the tri-state area around New York City, and an examination of the variability of modeled ozone concentrations due to variations in meteorology and emissions. easurements of ozone and precursors from monitoring sites in the tri-state area from 1980-1989 were analyzed. he results indicate a distinct downward trend in ozone levels over Connecticut during the period, however, no trend was evident in the ozone values over the New Jersey and New York areas. he photochemical modeling results from the Urban Airshed Model (UAM) revealed that peak ozone concentrations over Connecticut are strongly influenced by the wind fields input to the model. odel results also indicate that unless emissions reduction is substantial, variability in the meteorology can obscure any improvement in ozone levels.
