total precipitation variable in Aurora v1.5

#10

Hello,
I have been testing the Aurora v1.5 model. I see that it is possible to generate hourly predictions with v 1.5. I preformed inference with hourly output and I have 'scaled_tp_1h' for each hour such as at 7:00 UTC (first forecast hour), 8:00 UTC, 9:00 UTC and so on where the model was initialized with ERA5 data at 6:00 UTC and 00 UTC . My questions are following:

  1. Does 'scaled_tp_1h' at 7:00 UTC (first forecast hour) mean total accumulated precipitation from 6:00 UTC to 7:00 UTC (from initialization time to first forecast hour)?
  2. Does 'scaled_tp_1h' at 8:00 UTC (second forecast hour) mean total accumulated precipitation from 7:00 UTC to 8:00 UTC ( from first forecast hour to second forecast hour) or is it from 6:00 UTC to 8:00 UTC (from initialization time to second forecast hour)?

Thank you!
