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
