Tropospheric O3 and CO are major pollutants in the troposphere. Strong correlation between O3 and CO was observed during the DISCOVER-AQ aircraft experiment in July 2011 over the Washington-Baltimore area. The observed ...

This work presents a multi-scale modeling analysis approach to explore two subtopics pertaining to the chemistry-climate interaction: (1) ground-level ozone pollution in the United States and (2) the marine sulfur chemistry ...

Halogen-driven ozone and nonmethane hydrocarbon losses in springtime Arctic boundary layer are investigated using a regional chemical transport model (CTM). Surface observation of O3 at Alert and Barrow and aircraft ...

Ground-level ozone is an environmental and public health issue. Daily ozone forecasts are made to allow people to take precautions to protect their health. For this study, a prototype laser that measures ozone concentrations ...

In Part 1, we separated surface ozone time series collected from EPA monitoring sites in and around Georgia from 1980-2002 using a Kolmogorov -Zurbenko Filter to assess the influences associated with characteristic timescales ...

Biogenic isoprene plays an important role in tropospheric chemistry. We use HCHO column measurements by the Global Ozone Monitoring Experiment (GOME) to constrain isoprene emissions. Using the global Goddrad Earth Observing ...

The horizontal and vertical distributions of ozone and its precursors over North America during spring and summer are frequently determined by several factors: cloud convection, lightning NOx production, mixing depth, and ...
