New paper published describing nonspherical dust aerosol models

Illustration of the effects of the sphericity assumption on aerosol retrievals

This figure shows VIIRS SOAR AOD from (a) spherical and (b) spheroidal dust optical models, (c) AOD difference between the two, and (d) AOD longitudinal cross section along the dust transport path.

This paper describes an implementation of nonspherical dust optical property model in the Satellite Ocean Aerosol Retrieval (SOAR) algorithm, and the effects on the retrieval performance as compared to the spherical model. With this new change SOAR will provide a better view of aerosol optical properties over global water surfaces, as the nonspherical model significantly improves data quality for mineral dust aerosols. Note that this optical model has also been implemented in our SOAR AVHRR data set.
