Exploring the presence and the fate of small VOCs over the Southern Sea in the Austral Fall.
Abstract
Volatile organic compounds are omnipresent in the planetary boundary layer. Anthropogenic and Natural processes determine their presence and fate. These processes have been investigated for the better understanding in global oxidation capacity in past decades, but the remote marine boundary layer have been considered the least investigated area with a large uncertainty. We present a survey result of VOCs quantified using proton transfer reaction - time of flight - mass spectrometer in the Southern Ocean and Antarctic Peninsula in April of 2018 on R/V Araon owned and operated by Korea Polar Research Institute.
We will discuss determining factors of small OVOCs such as methanol, acetone, isoprene, and DMS over the Marine Boundary layers, particularly biotic and abiotic factors. We intend to use our observational constraints for the evaluation of our ability simulating OVOCs in the Southern Ocean by comparing with the CESM outp- Publication:
