Case study of the ASHE algorithm over North America

Paper about aerosol height and single scattering albedo retrieval

Application of the aerosol single-scattering albedo and height estimation (ASHE) algorithm to a smoke event observed over North America on 16 July 2014. (a) VIIRS RGB image with MODIS/Aqua fire mask in red dots, (b) VIIRS Deep Blue AOD, (c) OMPS UVAI, (d) retrieved SSA and (e) ATH from ASHE, and (f) CALIOP total attenuated backscatter profile with CALIOP-derived (black circle) and ASHE-retrieved aerosol heights (cyan circle).

Paper about MODIS Collection 6 Deep Blue, Dark Target, and 'merged' data sets

Example of the merging process for a MODIS Aqua granule over the Sahel. (a) A true-color image and (b) the algorithms selected for each individual retrieval . (c–e) Deep Blue (DB), Dark Target (DT) land/ocean, and merged AOD, respectively. Regions in grey lack valid AOD retrievals.
