Figure 3: SOA phase state and atmospheric implications.
From: Global distribution of particle phase state in atmospheric secondary organic aerosols
(a) Modelled mean vertical profiles of the inverse ambient temperature (1/T) relative to the glass transition temperature (Tg) of SOA (Tg/T) in specific areas over the Amazon basin, US, Europe, Sahara, India and East China as defined in Fig. 2. (b) Schematic of evolution of SOA phase state as a function of altitude and temperature, which has significant implications for CCN/IN activation, chemical aging and long-range transport. (c,d) Characteristic mixing timescales of (c) water and (d) organic molecules in SOA particles at the surface, 850 hPa and 500 hPa
