Hi! I'm Yu Yao.
A guy who is passionate about particles, clouds
and climate. I graduated from UIUC in 2021 and I am currently a postdoc associate at PNNL.
Cloud chemistry
Aerosol particle size distributions undergo physical and chemical changes during cloud processing. After cloud evaporation, the released particles can have different activation potentials than the particles before cloud processing because of changes in size and chemical composition.
In this project, we coupled the particle-resolved aerosol model PartMC-MOSAIC with the aqueous chemistry module CAPRAM 2.4 and designed cloud parcel simulations that mimicked several cloud cycles that a particle population may be exposed to in an urban environment

Particle radiation
Calculations of the aerosol direct effect on climate rely on simulated aerosol fields. The model representation of aerosol mixing state
potentially introduces large uncertainties into these calculations, since the simulated aerosol optical properties are sensitive to mixing state.
The aim of this project is to systematically quantify the impact of aerosol mixing state on aerosol optical properties.
