Airborne High Spectral Resolution Lidar Measurements of Aerosol Distributions and Properties During the NASA DISCOVER-AQ Missions Currently, near-surface air quality information (e.g. PM_2.5) must be inferred from column-integrated quantities (i.e. Aerosol Optical Thickness – AOT) obtained by passive remote sensing from downward-looking satellite instruments. Such retrievals must address the following questions:

What do we use for the height of the aerosols? Mixed Layer (ML) height?

Can we assume that near-surface aerosol extinction is about the same as the mean aerosol extinction in the ML?

How well is near-surface extinction related to surface PM_2.5?

How well can column AOT be used to infer near-surface aerosol extinction and PM_2.5?
