Slot: Percentile Reference Geographic Scope (percentile_reference_geographic_scope)

Geographic scope over which the reference distribution was computed. One of local_tract, local_county, local_climate_region, national.

Tier: recommended

Why this slot matters

A 95th percentile computed over one county and one computed over the whole nation are very different thresholds; the scope is what encodes "hot for here", and without it the threshold cannot be reproduced or compared across studies.

In plain terms

"Unusually hot" can mean hot compared to what is normal HERE, or compared to the whole country. This field says which area's history the comparison was made against.
