Short summary
Levels of hydroxymethanesulfonate (HMS) in a continental city and, for the first time, a marine atmosphere are reported. The effect of aerosol ionic strength (IS) on HMS formation was quantified; it first rises with increasing IS and then peaks at 4 mol kg−1 before declining. Given the IS range of marine (2–6) and urban (6–20 mol kg−1) aerosols and the clearly negative correlation between humidity and IS, moderate IS levels in humid conditions may notably boost ambient HMS formation.
