Microphysical and Macroscopic Properties of Ice Clouds and Mixed-Phase Clouds and Interactions with Aerosols: Linking in Situ, Remote Sensing Observations and Multiscale Models II

Submit an Abstract to this Session



Session ID#: 30794

Session Description:
Ice and mixed-phase clouds have large impacts on Earth’s climate. A composite analysis of in-situ, remote sensing observations and multi-scale model simulations is needed for understanding their formation and evolution.

We encourage studies that use model simulations and observations on various scales to investigate ice and mixed-phase clouds and aerosol-cloud interactions, and improve the capabilities of quantifying the impacts on regional and global climate. Relevant topics include: (1) observationally-based analyses of ice and mixed-phased clouds, aerosol-cloud interactions, partitioning between ice and liquid from cloud scales to global scale, (2) assessments of ice crystal and liquid droplet microphysical properties, (3) cloud macrophysical characteristics, including spatial heterogeneities and temporal variabilities, (4) sub-grid scale variabilities of relative humidity, water vapor, temperature and vertical velocity in model parameterizations, (5) radiative forcing of ice and mixed-phased clouds from observations, reanalysis data and model simulations, (6) observationally-constrained estimates of climate impacts of ice and mixed-phase clouds.
