Fig. 1: Novel observations of mixed-phase cloud top and interior phase.

a Schematic of “previous" and “new" methods to retrieve MPC supercooled liquid fraction from CALIOP observations. COD indicates the cloud's optical depth. b Global opaque cloud penetration depth in km (for a detailed data description see Guzman et al., 2017)34. c CALIOP lidar observations of the difference between cloud top SLF (%) and cloud interior SLF at the −20 °C isotherm. Line graph on the right shows a cross-section of the mean SLF difference for each latitude band. Note that across all latitudes, the difference is positive, i.e., cloud tops are more liquid (darker colours indicate more liquid cloud tops).
