Station Data (April 5 - August 5, 2014)
Input station data is presented in a plaintext columnar format with a header row. The metadata file provides station ID#, latitude, longitude, and English name. Each of the pollutant files lists the observed pollutant concentration at every station and each hour. Particulate matter pollution is in micrograms per m3, and all other pollution is in ppb.
