Data sets

Identification and classification of Cirrus (IC-CIR): A cirrus classification based on satellite and reanalysis data (2003–2013) E. Gryspeerdt, J. Quaas, T. Goren, D. Klocke, and M. Brueck

Ice crystal number concentration from satellite lidar-radar observations (DARDAR-Nice) O. Sourdeval, E. Gryspeerdt, M. Krämer, T. Goren, J. Delanoë, A. Afchine, F. Hemmer, and J. Quaas

Short summary
The concentration of ice crystals in a cloud affects both the properties and the life cycle of the cloud. This work uses a new satellite retrieval to investigate controls on the ice crystal concentration at a global scale. Both temperature and vertical wind speed in a cloud have a strong impact on the concentration of ice crystals. The ice crystal number is also related to the aerosol environment; defining this relation opens up new ways to investigate human impacts on clouds and the climate.
