Slot: Product Bounding Box (spatial_extent_bbox)

Bounding box of the source product (not the extracted subset), as [min_lon, min_lat, max_lon, max_lat].

Tier: recommended

Why this slot matters

The product footprint distinguishes "no value here" (the location lies outside the product's coverage) from "missing value" (the product covers it but the value is absent). Without it, out-of-extent patients look like data gaps and can be silently misinterpreted.

In plain terms

A bounding box is a rectangle drawn on the map that just barely contains all the data — four numbers giving its western, southern, eastern, and northern edges. Anything outside that rectangle was never covered by the dataset in the first place.
