From: Ice acceleration and rotation in the Greenland Ice Sheet interior in recent decades
a PISM simulated temperature profile at site T4, with the dotted line indicating the pressure melting point temperature. b Corresponding value of the flow law parameter, A. c Corresponding theoretical vertical velocity profile. For all subplots, the blue curves show the initial pre-warming state, while red curves show changes after the height of the initial basal temperate layer (light gray band, 26 m) has been raised ~ 18 m (dark gray band, 43 m).
