In Situ Measurements of Hydrogen Peroxide, Nitric Acid and Reactive Nitrogen to Assess the Ozone Sensitivity in Pingtung County, Taiwan
Hydrogen peroxide Nitric acid Reactive nitrogen Ozone sensitivity Smog production model
2016/3/28
This study was aimed to investigate the concentration of hydrogen peroxide (H2O2), nitric acid (HNO3) and reactive
nitrogen (NOy) at three sites in Southern Taiwan during 2003–2004. The mean H2O2 con...
Evaluation of Aerosol Particle Size at High Polluted Region in the World Using Direct Solar Radiation Measurements: Helwan as a Case Region

Measurements of Surface Ozone in Rural Site of India
Ozone production Meteorological parameters Rural site Precursor gases NOx titration
2016/3/30
It is known that the formation of surface ozone (O3) is chemically linked to the emissions of
major precursor gases, nitrogen oxides (NOx) and volatile organic compounds (VOC). This
chemical interde...
