We have near-real time aerosol gridded fields from GEOS-5 at our OPeNDAP
server:

http://opendap.nccs.nasa.gov:9090/dods/GEOS-5/yotc/0.25_deg/assim

Look at these collections:

  dds<http://opendap.nccs.nasa.gov:9090/dods/GEOS-5/yotc/0.25_deg/assim/tavg3_2d_aer_Cx.dds>

These are global datasets, some at 1/2 degree, others at 1/4 degree. GEOS-5
is a global data assimilation system, but no aerosol data is being
assimilated at this time. However, the model is driven by near-real time
MODIS derived biomass emissions.
