Atmospheric measurements with high spatio-temporal resolution

Sentinel-5 Precursor is designed to observe and monitor various atmospheric components and air quality every day. With an unprecedented resolution of 3.5 × 5.5 km2, the satellite and its on-board Tropospheric Ozone Monitoring Instrument (TROPOMI) can detect air pollution and its sources at sub-urban scale. This data is suitable for:

  • monitoring the amount of air pollution
  • assessing its impact on vegetation and public health
  • improving air quality models
  • issuing aviation warnings
  • tracking ship emissions

Nitrogen Dioxide

  • Nitrogen dioxide (NO2), a major air pollutant resulting from industrial process and traffic fuel combustion

Carbon Monoxide

  • Carbon monoxide (CO), an air pollutant formed by fossil fuel combustion and biomass burning processes

  • Formaldehyde (HCHO), and intermediate gas that eventually leads to CO2 formation and which indicates emissions by vegetation, fire, traffic and industrial sources activity
