Book Description
The formation of secondary organic aerosols through aqueous processes (aqSOA) has been identified as an important route in forming organic aerosols; however, many aspects of this formation are still uncertain. One main uncertainty is the nature by which these aqueous compounds are formed, whether the formation is reversible, irreversible, or a mixture of both. To date, there are no ambient measurements to quantify or constrain the relative contributions of reversible/irreversible aqSOA. Hence, we have developed an online method to simultaneously measure water-soluble organic carbon in the gas (WSOCg) and particle (WSOCp) phases to characterize the reversible and irreversible uptake of water-soluble organic gases to aerosol liquid water (ALW) across the different seasons in Maryland located in the eastern United States.
