GreenEO: Urban Air Quality Monitoring Overview

WP2 Overall Objectives

The overall objective of WP2 is to harness data from MTG-S and EPS-SG satellites for urban-scale air quality applications.

Satellite Programs Overview

• MTG-S: Geostationary satellites with a planned launch of MTG-S1 in July 2025. Key instruments include:

  • Infrared Sounder (IRS): Provides hyperspectral data for vertical temperature and humidity profiles.
  • Sentinel-4/UVN Instrument: Focuses on monitoring atmospheric composition and air quality over Europe.

• EPS-SG: The second generation of polar-orbiting satellites, comprising two types: Metop-SGA and Metop-SGB. Only Metop-SGA will carry the Sentinel-5 instrument.

Sentinel-4 Instrument on MTG-S

• Purpose: To monitor air quality, trace gases, and aerosols over Europe with a spatial resolution of approximately $8 ext{ km} imes 8 ext{ km}$ and hourly updates during daylight.
• Monitored Constituents: NO2, O3, SO2, HCHO, CHOCHO, and aerosols.
