Scorecard for IFS cycle 41r1

Score card provides a quick visual overview over the performance of the CY41r1 scores compared to CY40r1. It is a simplified summary of verify error plots of various domains, scores, parameters etc.

Each error plot is converted into a sequence of symbols (e.g. ▼ ▾ ▾ ░ ░ ░ ░ ▴ ▲ ▲) where each symbol indicates for a given time step whether or not the CY41r1 is significantly better or worse than the CY40r1.

Symbol legend: for a given forecast step... (d: score difference, s: confidence interval width)
▲ CY41r1 better than CY40r1 statistically highly significant (the confidence bar above zero by more than its height )(d/s>3)
▴ CY41r1 better than CY40r1 statistically significant (d/s≥1)
░ CY41r1 better than CY40r1, yet not statistically significant (d/s≥0.5)
░ not really any difference between CY40r1 and CY41r1
░ CY41r1 worse than CY40r1, yet not statistically significant (d/s≤-0.5)
▾ CY41r1 worse than CY40r1 statistically significant (d/s≤-1)
▼ CY41r1 worse than CY40r1 statistically highly significant (the confidence bar below zero by more than its height) (d/s<-3)
