Data for 'Pollutant emission reductions deliver decreased PM2.5-caused
  mortality across China during 2015–2017'

The dataset consists of three .csv encoded using UTF-8.
The files contain the 2015-2017 trends in pollutant concentrations calculated
  from the measurement data and model runs
The results are shown for each pollutant are shown at each station location
  (where quality control checks were passed). 
The files contain the trends in the pollutants:
 - Particulate matter with a diameter less than 2.5 micrometres (PM2.5)
 - Ozone Maximum Daily 8-hour mean (O3_mda8)
 - Nitrogen Dioxide (NO2)
 - Sulphur Dioxide (SO2)

Columns:
 - station (code or short name of measurement station)
 - pollutant
 - trend (in units of micrograms per metre cubed)
 - trend_% (in % relative to the the 3-year mean)
 - mean (3-year mean in units of micrograms per metre cubed)
 - latitude
 - longitude
 - station_name_en (long name of station automatically translated from Chinese)
 - station_name_zh (long name of station in Chinese)
