  2. CONTRIBUTION TO GMES TROPOMI • UV-VIS-NIR-SWIR nadir view grating spectrometer. • Spectral range: 270-500, 675-775, 2305-2385 nm • Spectral Resolution: 0.25-1.1 nm • Spatial Resolution: 7x7km2 • Global daily coverage at 13:30 local solar time. • Total columnO3, NO2, CO, SO2,CH4, CH2O,H2O,BrO • Tropospheric columnO3, NO2 • O3 profile • Aerosol absorbing index, type, optical depth sentinel-5 precursor COPERNICUS/GMES ATMOSPHERE MISSION IN POLAR ORBIT • 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.

  3. 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.

  4. Long Term Monitoring

  6. 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.

  8. TROPOMI Status • I-CDR successfully completed • Modules are being assembled • Start of calibration: Summer 2014 • Instrument delivery: beginning 2015 • Planned launch date: Q1 2016

  9. Performance Overview

  10. From OMI to TROPOMI • 6x higher spatial resolution7x7 km2 vs. 13x24 km2 • 1-5x higher signal-to-noise • Variable binning scheme • better cloud informationfrom the oxygen A+B bands • CO and CH4 observationsfrom the SWIR band • Data rate ~20x OMI

  13. 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. veefkind@knmi.nl www.tropomi.eu www.temis.nl www.knmi.nl/omi http://www.esa.int/esaLP NO2 SO2 AOT HCHO
