So even if cosmic rays are linked to
cloud formation, all they'll find is the
cloud formation 50 years ago is similar to now and has little to no
impact on the last 30 years of long term global warming.
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.
