Raw data

  • Check on outliers
  • Overwriting of existing data
  • (re)calculation of all aggregations and statistics
  • Ad-hoc action based on feedback users

improving the quality future
Improving the quality - future
  • Correction factor PM10, PM2.5
  • More sophisticated outlier checking
  • Gaps in time
  • Gaps in spatial coverage
  • Phantom stations
  • Information on cities
