 MULTI-SCALE MODELING OF AEROSOL INTERACTIONS WITH CLOUDS AND RADIATION\n\n 
 \n\nAbstract: Aerosol effects on climate remain one of the largest sources 
 of uncertainty in quantifying anthropogenic climate change\, despite increa
 ses in model complexity. Aerosol interactions with clouds and radiation dep
 end on the size\, shape\, and chemical composition of individual particles\
 , as well as small-scale heterogeneity in environmental properties. However
 \, this small-scale heterogeneity is not easily represented in large-scale 
 atmospheric models. In this talk\, I will describe process-level studies th
 at reveal large errors in the cloud condensation nuclei activity and aeroso
 l optical properties stemming from unresolved heterogeneity in particle and
  environmental properties. I will then describe how recent advances in aero
 sol microphysics simulations can be combined with machine learning to provi
 de accurate and efficient aerosol representations in large-scale models. \n
 \n \n\nBio: Laura Fierce is an Earth Scientist in the Atmospheric Sciences 
 and Global Change Division at Pacific Northwest National Laboratory. Her re
 search focuses on advancing the predictive understanding of aerosol effects
  on clouds and radiation through improved representation of multiscale aero
 sol processes. Dr. Fierce began her career in the DOE national laboratory s
 ystem as a postdoctoral fellow\, funded by a NOAA Climate & Global Change P
 ostdoctoral Fellowship\, and then a scientist at Brookhaven National Labora
 tory. Now at Pacific Northwest National Laboratory\, she specializes in par
 ticle-based methods for simulating aerosol size-composition distributions t
 hrough the development of quadrature-based moment methods and the applicati
 on of Monte Carlo methods.\n\n​​​​​
