Advance the Understanding of Clouds and Aerosols by Linking In-Situ Measurements, Satellite Observations and Climate Model Simulations

Ice and mixed-phase clouds play an essential role in Earth’s weather and climate. To advance the understanding of cloud formation and evolution, the first part of this talk will interconnect laboratory calibrations, in situ observations and numerical model simulations. Analysis of in situ observations will be shown for eight NSF field campaigns, covering from 87°N to 75°S. A survey of cloud microphysical properties, dynamical and thermodynamic conditions, and aerosol number concentrations will be conducted. Specifically, this study aims to bridge the gaps between aircraft observations and climate model simulations, which have different horizontal scales ranging from 100 meters to 100 kilometers. The second part of this talk focuses on satellite-based PM2.5 estimates in California. A fusion of ground monitors, satellite-derived PM2.5 concentrations and dispersion modeling will be presented. Analyses of PM2.5 emissions from California wildfires in 2017 will be shown.
