Abstract:

The composition and physical properties of atmospheric particles play a critical in Earth's radiative balance and are major sources of uncertainty in understanding our global climate. Atmospheric particles are produced through a variety of processes and their atmospheric impacts depend on multiple factors, like the composition, size and number concentration. Particularly, the composition, formation and growth of ultrafine particles, defined as particles with a diameter less than 100 nm, are of particular interest to investigate due to their ability to directly serve as cloud condensation nuclei (CCN). However, these various chemical and physical properties of ultrafine particles are largely dependent upon the environment they originate from. Therefore, studying the composition of ultrafine particles across various locales is extremely important and these results can be incorporated into building better global prediction models of climate. This dissertation investigates the chemical composition of ultrafine particles across the Amazon Basin, commonly referred to as the "green ocean," and over marine environments, or the "blue ocean."
