Slot: Buffer Radius (Metres) (linkage_buffer_radius_m)

Buffer radius in metres for buffer-aggregation strategies.

Tier: conditionally_core

Why this slot matters

For buffer strategies the radius defines the exposure footprint: a 500 m and a 5 km buffer around the same residence can average over very different air or heat conditions, so the assigned value is not reproducible without it.

In plain terms

When exposure is averaged over a circle drawn around a person's home, this is how wide that circle is, in metres.
