Slot: Heat Metric Family (heat_metric_family)

The family of heat metric this variable represents.

Tier: core

Why this slot matters

Tmax, Heat Index, WBGT, and a heat-wave flag are distinct exposures with distinct health associations; without the family, values from different metrics are indistinguishable and get pooled as if they measured the same thing.

In plain terms

There are many different "heat numbers" — plain air temperature, composite scores that also fold in humidity, wind and sunshine, or a simple yes/no heat-wave flag. This field says which kind of heat number the record is about.
