Research Summary

The overarching theme of Dr. Hallar's research is using high quality measurements of trace gases, aerosol physical and chemical properties, and cloud microphysics to understand connections between the biosphere, atmosphere, and climate, along with the impact of anthropogenic emissions on these connections. More specifically, currently her research uses high elevation sites, combined with airborne measurements, to study the formation processes of Cloud Condensation Nuclei and Ice Nuclei.
