Illustration of the effects of the sphericity assumption on aerosol retrievals

New paper published describing nonspherical dust aerosol models

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.

Validation of the ASHE algorithm, from Lee et al (2016)

New papers in Aerosol and Air Quality Research special issue

This figure from Lee et al. (2016) shows (top) time series of ASHE and MPLNET aerosol top height (ATH), (middle) VIIRS and AERONET AOD, and (bottom) ASHE and AERONET SSA from the complete algorithm (left) and simplified algorithm (right). Only best QA data are shown. The MPLNET and AERONET data are presented only if there are ASHE retrieved ATH data, while the gray dots represent the full MPLNET/AERONET data records. The black vertical line separates 2013 and 2014.


Paper about MODIS Terra Deep Blue Collection 6 validation and stability

This figure shows the global over land area-weighted time series of DB (a) AOD at 550 nm and (b) AOD anomaly and decadal trends, from MODIS Terra (red) and Aqua (blue), and (c) the time series and decadal trend in the Terra-Aqua AOD difference. Uncertainties in calculated trends are presented as 90% confidence intervals.
