TROPOMI on Sentinel 5 Precursor
Peter van Velthoven, on behalf of:Pepijn Veefkind, Ilse Aben, Quintus Kleipool, Pieternel Levelt, & the TROPOMI team
• The ESA Sentinel-5 Precursor (S-5P) is a pre-operational mission focussing on global observations of the atmospheric composition for air quality and climate.
• The TROPOspheric Monitoring Instrument (TROPOMI) is the payload of the S-5P mission and is jointly developed by The Netherlands and ESA.
• The planned launch date for S-5P is 2016 with a 7 year design lifetime.

TROPOMI Science Objectives
• To better constrain the strength, evolution, and spatiotemporal variability of the sources of trace gases and aerosols impacting air quality and climate.
• To improve upon the attribution of climate forcing by a better understanding of the processes controlling the lifetime and distribution of methane, tropospheric ozone, and aerosols.
• To better estimate long-term trends in the troposphere related to air quality and climate from the regional to the global scale.
• To develop and improve air quality model processes and data assimilation in support of operational services including air quality forecasting and protocol monitoring.

Suomi-NPP - S5P formation Flying
• S-5P is planned to observe within 5 min. of Suomi-NPP.
• Primary goal is to use VIIRS cloud mask for S-5P methane observations.
• Other opportunities:
‣ TROPOMI-VIIRS cloud andaerosol combined products.
‣ TROPOMI-OMPS-CRIS ozone profiles.
‣ TROPOMI-OMPS inter-calibration.

Summary & Outlook
• TROPOMI will be a major step forward for atmospheric composition observations due to improved spatial resolution & sensitivity.
• The high spatial resolution provides new opportunities, while at the same time being challenging for the Level 2 product development.
• Sentinel 5 Precursor will connect to the geostationary missions providing in-flight CAL/VAL and inter-comparison opportunities.
