<span style="font-family: Aptos; font-size: 16px;">ABSTRACT: </span><span style="font-family: Aptos, Arial; font-size: 12pt;">Giant sea salt aerosol (GSSA; dry radius > 1 µm) plays a critical role in Earth’s radiative budget, aerosol–cloud interactions, and
potentially warm-rain initiation, yet major uncertainties remain in its production, transport, and global distribution. Historically, these knowledge gaps have been driven by limited access to affordable, high-resolution observational tools capable of resolving
the largest sea-salt particles in sufficient detail. Recent advances in low-cost in-situ instrumentation have expanded the capacity to measure GSSA size distributions (GSSA-SDs) across a wider range of field environments, including regions where traditional
instruments would have been prohibitively expensive or logistically impractical. Increased observations combined with reanalysis tools and models have led to novel insights of these giant aerosol concentrations globally, as well as important assessments of
their representation in models. Overall, instantaneous environmental conditions alone can misrepresent the processes controlling GSSA abundance; instead, air-mass history and cumulative exposure to surface wind and ocean state exert strong influences on the
concentrations measured at a given time. This talk focuses on 1) the importance of accessible aerosol observations, as well as 2) some key nuances of interpreting these field observations within a broader environmental context.</span></div>
