Jackson, R.C., G.M. McFarquhar, A. Fridlind, and R. Atlas, 2015: The dependence of cirrus gamma size
distributions expressed as volumes in N0 - λ - μ
phase space and bulk
cloud properties on environmental conditions: Results from Small Ice Particles in Cirrus Experiment (SPARTICUS).
These include the vertical motions of
clouds, all the radiative - energy - transport characterizations of the non-vaporous (gaseous)
phases of water in the
clouds, the vertical locations of the
cloud tops, the
distributions of the non-vaporous
phases of water within the
clouds, and all aspects of precipitation of liquid - and solid -
phase water from the
clouds.
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.
