Shown are retrieved aerosol profiles from the NASA Langley High Spectral Resolution Lidar (HSRL) acquired 7 March 2006 on a 150 km flight leg over the Mexico City region: (a) backscatter, (b) extinction, (c) extinction-to-backscatter ratio, (d,e) depolarization ratio at 532 and 1064 nm, respectively, and (f) 1064-to-532 nm backscatter wavelength dependence. The HSRL provides direct measurement of aerosol extinction, which is important for estimating the radiative impact of the aerosols. Data products (c)-(f) are intensive observables (i.e., depend only on aerosol type) and indicate that the aerosol type varied significantly across the region covered by this flight leg. For details, see the paper by Hair et al., pp. 6734-6752.
