The key to this understanding are the concepts
of a «torque» and the
of natural power
of «swirling vortices» as these phenomena that
relate to the
role of the atmosphere, the
oceans, the Earth's «molten outer core,» and formation
of Earth's magnetic field on climate change.
Topics that I work on or plan to work in the future include studies
of: + missing aerosol species and sources, such as the primary oceanic aerosols and their importance on the remote marine atmosphere, the in - cloud and aerosol water aqueous formation
of organic aerosols that can lead to brown carbon formation, the primary terrestrial biological particles, and the organic nitrogen + missing aerosol parameterizations, such as the effect
of aerosol mixing on cloud condensation nuclei and aerosol absorption, the semi-volatility
of primary organic aerosols, the importance
of in - canopy processes on natural terrestrial aerosol and aerosol precursor sources, and the mineral dust iron solubility and bioavailability + the change
of aerosol burden and its spatiotemporal distribution, especially with regard to its
role and importance on gas - phase chemistry via photolysis rates changes and heterogeneous reactions in the atmosphere, as well as their effect on key gas - phase species like ozone + the physical and optical properties
of aerosols, which affect aerosol transport, lifetime, and light scattering and absorption, with the latter being very sensitive to the vertical distribution
of absorbing aerosols + aerosol - cloud interactions, which include cloud activation, the aerosol indirect effect and the impact
of clouds on aerosol removal + changes on climate and feedbacks
related with all these topics In order to understand the climate system as a whole, improve the aerosol representation in the GISS ModelE2 and contribute to future IPCC climate change assessments and CMIP activities, I am also interested in understanding the importance
of natural and anthropogenic aerosol changes in the atmosphere on the terrestrial biosphere, the
ocean and climate.
