Temporal and Spatial Variability of Clouds and Related Aerosols

This chapter contains sections titled: Hygroscopic Properties of Atmospheric Aerosols Appear to be Better Constrained than Other Key Parameters of Warm Cloud Formation, Ice Nuclei and Ice Microphysics Still Pose Many Open Questions, The Confounding Influence of Meteorology, Evidence for Large-scale Aerosol Impacts on Cloud Albedo, Cloud Amount, and Precipitation Remain Ambiguous, A Major Motivation to Study Aerosols and Climate Is to Understand 20

-century Temperature Change, Since Some Global Warming Signals Are Now Becoming Evident, We Should Search for Associated Cloud Changes, Existing Cloud, Aerosol, and Radiation Records Need to be Reprocessed, and the Continuity of the Current Observing System Must be Guaranteed, New Strategies Are Required to Observe Key Variables More Accurately for Understanding Perturbed Clouds in the Climate System, Acknowledgments, References
