The pargasite package offers tools to estimate and visualize levels of major pollutant levels (CO, NO2, SO2, Ozone, PM2.5 and PM10) across the conterminous United States for user-defined time ranges. It provides functions to retrieve pollutant data from the Environmental Protection Agency's (EPA) Air Quality System (AQS) API service for interactive visualization through a Shiny application, allowing users to explore pollutant levels for a given location over time relative to the National Ambient Air Quality Standards (NAAQA).
We have no affiliation with the EPA.
