- Why it was chosen
- Extending river-flood warnings to urban flash floods with up to 24 hours' lead time, alongside NWS comparisons, reveals coverage differences for AI warnings in the Global South.
A model scores each item twice, independently, against one written standard, out of 100. An item is admitted only when the two scores add up to twice the threshold. The threshold is set per source tier.
