NOAA REFS forecast, 3 hourly, virtual validation report

This dataset validation report plots a sample of values from the NOAA REFS forecast, 3 hourly, virtual dataset over time and across space, comparing where possible to a previously validated reference dataset. It also reports the quantity of unavailable values and their associated timestamps. These analyses are one layer of a multi-layered dataset validation process we perform at dynamical.org and also provide users a preview of the dataset contents.

Report generation start time: 2026-10-13T21:02:28 UTC

Summary

This dataset has been validated and is ready for experimental use. NOAA RRFS/REFS is pre-operational and under development, so expect some changes to model output. The data contains selected instances of implausible outputs, like strongly negative precipitation in specific forecasts, and flash flood guidance probabilities are partially missing in some forecasts. See the review notes below.

comment Threshold applies to the preceding 24 hours of accumulation. Published every 3 forecast hours from lead 24 hours. Neighborhood probability of 24 hour precipitation above the 5 year average recurrence interval depth. Probabilities compare precipitation with a spatially varying guidance or recurrence-interval depth. Negative values are unavailable thresholds blended into neighboring cells by smoothing; positive values near coverage boundaries can also be biased low. Mask values < -0.1.
