Facilitating the Next Generation of Air Quality Science: Synergy of NASA’s Ground-Based Observation Networks

Dr.Xiaoguang Xu, Joint Center for Earth Systems Technology.

The proposed work will combine observations of winds, aerosols, and trace-gas pollutants to complement and extract new science from NASA’s existing network of Tropospheric Ozone Lidar (TOLNet) and Pandora spectrometers, focused on regions near complex coastal terrain. The following are two overarching questions from which the tasks of this proposal are derived. Q1) How can observations of ozone from TOLNet and Pandora be combined with regional in-situ measurements to capture and quantify the evolution and impact of ozone episodes? Q2) Do chemical transport models and planned satellite retrievals properly represent observations of vertically resolved and columnated ozone from TOLNet and Pandora.
