Staff research

Exposure Explorer — Research view

The precise (staff) exposure tier: cohort rollups for each measurement type, aggregated to county. Particulate exposures are shown against absolute EPA AQI bands; microbial and chemical exposures use neutral relative levels — never a safety threshold.

Precise (staff) tier — cohort exposure rollups aggregated to county. Per-subject city-level data is available only via the DUA-gated Limited Data Set export, not shown here.

    Geography

    Exposure map

    Precise (staff) county cells on the bundled offline US map (no tiles). Sub-k pilot counties surface here; the public map coarsens/suppresses them. PM uses EPA AQI; microbial/chemical use relative levels.

    Per-subject

    Exposome report

    Real per-Subject exposome, at the city Limited Data Set tier under a Data Use Agreement (ADR 0018/0021). Subjects are pseudonymous; PM is absolute EPA AQI, microbial/chemical bands are relative prevalence — not safety.
