Data and code for: Unequal ground truth and asymmetric error in global satellite PM2.5 exposure estimates

Data and analysis code accompanying the manuscript "Unequal ground truth and asymmetric error in global satellite PM2.5 exposure estimates". The deposit contains the station inventory of 19,757 openly available PM2.5 monitoring locations across 151 countries with their provenance classification, the pooled ground records and product samples for the 8,823 analysed stations, every analysis script, the console logs of the cluster runs cited in the paper, and a SHA-256 manifest of all files. The pipeline is deterministic at a fixed seed. README.md documents the analysis in order and gives the commands that reproduce each published table and figure.
