For the highest-performing model from the top 10 teams, figures show global maps of aggregated RPSSs for each variable and forecast window. Note that during the early stages of a competitive period, only a limited number of forecast initializations may be available to compute grid-point values.
Percentage of positive period-aggregated RPSSs
These figures display the total percentage of positive RPSS values, i.e. points where forecasts outperform climatology, for each submitted model. Percentages are calculated relative to the total number of valid grid points. For example, for near-surface temperature (tas), only grid points with more than 50% land cover are included in the calculation.
