Abstract
Trace gases, aerosol particles, and clouds interact with each other and pose challenges in terms of how best to simulate their spatiotemporal profiles. Surface and airborne field work help increase understanding of these atmospheric components. This talk will present on recent field work in diverse regions: Arizona, northwest Atlantic, southeast Asia. Arizona has experienced rapid population growth in the 2000s and represents a semi-arid region with complex topography and the influence of the North American Monsoon. There have been limited studies related to atmospheric chemistry in this state and recent developments will be discussed.
As aerosol-cloud interactions are linked to the largest uncertainty in estimates of total anthropogenic radiative forcing, the NASA ACTIVATE mission (2020-2022) was conceived to acquire a useful dataset to further advance this field of research. This talk will introduce this mission and provide highlights of its operation and selected science outcomes to date.
Lastly, the NASA CAMP2Ex mission was conducted in summer 2019 to better understand the interactive role of aerosol particles, clouds, and atmospheric radiation within the Maritime Continent’s complex southwest monsoonal environment. Highlights will be discussed from the campaign focused on aerosol-cloud-meteorological interactions.
