Exposure Data from the Atmospheric Composition Analysis Group at Washington University in St. Louis

This page describes the PM2.5 exposure datasets published by the Atmospheric Composition Analysis Group at Washington University in St. Louis, and the Dorieh utilities and pipelines that download them, convert component percentages to absolute values, and combine the results into a single tabular dataset.

We use monthly data for absolute PM2.5 values and annual data for PM2.5 and its components. The absolute values are provided in ug/m3 units, but the PM2.5 components are published as percentage values, which are not usable for aggregation; Dorieh utilities convert them into absolute values before combining the results.
