I was also wondering how the sulphates were being discerned --
weather satellites have visible, water vapor and several IR
instruments. Perhaps sulphates are detectable within some
of the IR channels.
Space.com listed it as a simulation.. however it looks like
a composite of real satellite data possibly composited with
simulated data. So the bloom may be fantasy. Hence my
questions.
I've been looking at 'full disc' weather satellite imagery
(Dundee!) for > decade. All I can say is if the space.com
animation is purely a numerical simulation it's very impressive.
It looks plausible.
