🗂️ Datasets (files)

This folder contains open City Scanner data sets collected in four deployments in three cities. Raw sensor readings were collected and calibrated following standardized air sensor performance evaluation guidelines recommended by the U.S. EPA. The general method is presented in the following diagram and details can be found in the open source calibration handbook.
