Description:

This is the 2nd of two articles of my past work on light absorption by remote aerosols, published in the journal, Atmospheric Environment, Vol. 30-1, Jan. 1996.   The EPA recently mandated tougher fine particle (PM 2.5) pollution standards, requiring a reduction of 70% in black carbon light-absorbing particles--based upon this work, I recommended just that reduction to the EPA ten years ago.   They're just getting around to appreciating the problem of black carbon emissions, rather than just focusing on "greenhouse gases," after that long a time.
