: Detailed analysis of the stratosphere (ozone layer preservation) and the troposphere (photochemical smog formation).

: Emissions from fossil fuel combustion (CO₂, NOₓ, SO₂, PM) act as "climate forcers". For instance, while sulfate aerosols reflect sunlight to cool the planet, black carbon (soot) absorbs heat and accelerates warming.

: Fossil fuels are identified as the largest contributor to global climate change, responsible for roughly 90% of all carbon dioxide emissions .

: Established the core framework for atmospheric engineering.

: Extensive coverage of the formation, growth, thermodynamics, and optical properties of airborne particulate matter, including secondary organic aerosols .
