New Mexico PM2.5 concentrations by ZIP code for 4 smoke exposure estimates

This repository contains daily ZIP code-level data for four wildfire smoke PM2.5 exposure estimates and daily heat index used in our epidemiological analysis of cardiorespiratory emergency department visits in New Mexico during the 2022 wildfire season. The smoke exposure datasets include (1) a regulatory-only product, (2) a regulatory + PurpleAir kriged product, (3) the NOAA HMS smoke plume–masked product, and (4) a CMAQ-modeled product with bias correction. Heat index values were derived from gridded meteorological data and aggregated to ZIP codes. These datasets support investigations of how exposure measurement choices influence health effect estimates in wildfire smoke research.
