Fig. 6: Error variation with resolution over time.

a The dimensionless RMSE between the optimal 2 km PDF and coarser resolutions. b The discrepancy between the optimal 2 km CDF and coarser resolutions. In both panels, the melt average is M = 20 ma−1. Colours indicate resolution: 2 km (blue), 3 km (orange), 4 km (green), 5 km (red), 6 km (purple), 7 km (brown), 8 km (pink).
