Dr. Fridlind's studies of cloud microphysical properties and processes have concentrated at the intersection of detailed models and rich observational data sets, with an emphasis on aerosol-cloud interactions in ice-containing clouds that are most relevant to climate. Her studies have spanned mixed-phase stratiform clouds from Arctic to Antarctic, tropical to mid-latitude deep convection, mid-latitude continental cumulus and synoptic cirrus, and subtropical stratocumulus. She is a developer of ice microphysics schemes in the DHARMA large-eddy simulation code and, more recently, ice- and mixed-phase microphysics and macrophysics of stratiform clouds in the GISS ModelE3 Earth system model.
