Range-corrected signal

Ozone retrieval (10-min resolution)

The ozone distribution pattern (low ozone at about 3-6 km) is similar as June 26 data. However, the boundary layer ozone concentrations decrease. This is consistent with the EPA surface data. The aerosol concentrations from both DIAL and ceilometer data decrease too compared with June 26. This is why we get a better SNR than June 26. These data suggest a strong correlation between ozone and aerosol activities.
