Excited to share our work on aerosol pH, led by grad stdnt J. Campbell. In short, temp largely modulates aerosol pH, which, in turn, drives aerosol chemistry. This collaborative effort involves R. Weber @LAPI_epfl @ShipleyRobinson @ProfPeteD @ArcticKerri science.org/doi/10.1126/scia…

Enhanced aqueous formation and neutralization of fine atmospheric particles driven by extreme cold

Aqueous aerosol formation is believed to occur in clouds/fogs; measurements expand possible regions of pH-dependent formation.
