Slot: Native Spatial Resolution (m) (native_spatial_resolution_m)

Native spatial resolution of the source product in metres. Daymet = 1000, GridMET ≈ 4000, NARR ≈ 32000.

Tier: core

Why this slot matters

Exposure misclassification scales directly with cell size: a value from a 32 km NARR cell averages over an entire metro area while a 1 km Daymet cell resolves a neighbourhood. Without the resolution, downstream users cannot judge how precise a per-patient exposure really is or whether two studies' values are comparable.

In plain terms

Gridded environmental data divides the world into square tiles, like pixels in a photo, and reports one value per tile. This field says how wide each tile is in metres — small tiles give a sharp picture of local conditions, big tiles give a blurry average over a large area.
