Figure 2 : Cloud liquid water simulated by ERA-Interim and detected by CALIPSO lidar on 12 January 2016.

From: January 2016 extensive summer melt in West Antarctica favoured by strong El Niño

Figure 2

(a) Map of cloud liquid water path (CLWP) simulated by ERA-Interim for 06:00 UTC on 12 January 2016. The black star denotes the location of WAIS Divide. The two pink lines represent the CALIPSO satellite trajectories corresponding to the vertical profiles shown in b,c. The points labelled A, B, C and D along these trajectories are identical to those shown at the bottom of the vertical profiles. The black triangle denotes where rain was witnessed by a field party on 12 January (Dr Huw Horgan, Victoria University of Wellington, personal communication). (b,c) Vertical profiles of ice/water phase retrievals from CALIPSO Lidar Level 2 data products over West Antarctica for two time windows on 12 January 2016 (4:15–4:29 UTC in b and 7:33–7:46 UTC in c). The thin black line represents the surface topography.
