Abstract (including Motivation, Hypothesis and Method)

The only difference between this experiment and the PRX is that the forecast is truncated to T126 L28 at hour 84. The motivation for this experiment is that it is quicker to run this way and that recent studies show that forecasts truncated after day 3 may have at least as much skill in days 4 through 7 as the full resolution forecasts.

Conclusion

Truncating at hour 84 proved viable. The procedure was essentially moved to the PRX.
