The plot below shows evolution of 2-metre temperature forecasts for the position of Polarstern (84.3N, 14.75E), valid for 19 April 12UTC. The plot includes ENS forecasts (Blue box-and-whiskers), HRES (red dot) and model climate (red box-and-whisker). The observation from Polarstern was -0.1C. The probability boundaries for the box and whiskers are (1-99, 10-90, 25-75 and median as dot).
