Slot: Exposure Model (exposure_model)

The exposure-model object describing how values were produced. Bound to ExposureModel (see envar_model). Readable rename of the profile's methodology anatomy slot, narrowed to the model itself: other methodology-adjacent concerns (source dataset, tool run, provenance chain, derived heat metric) are surfaced as separate envar-extension slots.

Tier: core

Why this slot matters

The same quantity can be estimated by station interpolation, satellite retrieval, or model reanalysis, each with different inputs and biases; without the model description, values from different products get pooled as if equivalent and their systematic differences stay invisible.

In plain terms

Most exposure values are not direct readings from an instrument at someone's house — they are estimates computed from weather stations, satellites, or models. This block says which estimation method produced the numbers and what went into it.
