“…The atmospheric formation and fate of HPMTF and its potential impact on sulfate aerosol formation is a topic of active research in the atmospheric chemistry community. In addition to the present HPMTF experimental laboratory studies and that in other laboratories, ,,,, there have been a number of field ,, and atmospheric modeling studies of HPMTF. ,− Field observations have demonstrated that HPMTF is present in the global marine boundary layer ,, and the Amazonian basin with a diurnal profile and that it is efficiently removed when encountering a cloud, , which implies efficient uptake by cloud droplets. The uptake coefficient and fate of HPMTF and its degradation mechanism in the aqueous phase, however, remain a research topic of interest …”
