Monoterpenes, primarily emitted by terrestrial vegetation, can influence atmospheric ozone chemistry, and can form precursors for secondary organic aerosol. The short-term emissions of monoterpenes h...
Variable CCN formation potential of regional sulfur emissions
Variable CCN formation potential regional sulfur emissions
2009/6/2
Aerosols are short lived so their geographical distribution and impact on climate depends on where they are emitted. Previous model studies have shown that the mass of sulfate aerosol produced per uni...
