Analyses of the ground and aircraft data performed by Setyan et al. (2012), Shilling et al. (2013), and Kleinman et al. (2016) showed that organic aerosol production increased
when human - caused emissions from Sacramento mixed with air rich in
isoprene, an organic compound wafting from many plants that originate in the area's foothills.
Increased biomass can lead to increased emissions of biogases such as dimethyl sulfide and
isoprene, which
when oxidized in the atmospheric form sulphate and organic aerosols that can nucleate clouds, increasing cloud cover and planetary albedo — the CLAW Hypothesis.
