Short summary
Atmospheric aqueous chemistry can have profound effects on our environment, as illustrated by historical data from Whiteface Mountain (WFM) that were critical for uncovering the process of acid rain. The current study updates the long-term trends in cloud water composition at WFM for the period 1994 to 2021. We highlight the emergence of a new chemical regime at WFM dominated by organics and ammonium, quite different from the highly acidic regime observed in the past but not necessarily
clean.
