Description:

Ozone (O3) pollution episodes often occur on hot days in summer in the New York City (NYC) metropolitan area and its downwind coastal area due to large amounts of urban emissions, chemical productions, and meteorological and regional transport effects. To understand the formation process of high ozone, it is important to observe the ozone vertical distribution and its evolution. In this chapter, we reported an Ozone Differential Absorption Lidar (DIAL) developed at the City College New York (CCNY) and present the initial observations. The results show that the CCNY O3-DIAL is able to retrieve O3 concentration from 0.2 to 8.5 km altitude with 10-minute time resolution, depending on operation conditions. The O3 retrievals from the near-range and far-range channels have good consistency at 0.9–1.8 km altitude. In addition, under favorable weather conditions, the O3 retrievals at near-surface show a consistent temporal variation with the co-located in situ O3 measurements. Our observation cases indicated the elevated O3 concentration above the planetary boundary layer (PBL) which might be associated with the regional pollution transport such as the wildfire smoke plumes. The CCNY-Ozone DIAL will be installed in a trailer in the near future which allows mobile observation for the field campaign.
