SENTINEL-5P+ INNOVATION OCEAN COLOUR (S5P+-I-OC)

ALFRED WEGENER INSTITUTE (DE)

Summary

The S5P+I-OC project will explore the capacity of the Sentinel-5p TROPOMI data to provide novel Ocean Colour (OC) products. More specifically, the objectives of this S5P+ Innovation activity are to:

  1. develop a solid scientific basis for the application of S5P data within the context of novel scientific and operational OC products applications;
  2. assess existing algorithms which have been used for OC product retrievals from SCanning Imaging Absorption Spectro-Meter for Atmospheric CHartographY (SCIAMACHY), Ozone Monitoring Instrument (OMI) and Global Ozone Monitoring Experiment (GOME-2);
  3. develop novel OC products and retrieval methods that exploit the potential of the S5P mission’s capabilities beyond its primary objectives, in particular, the chlorophyll-a concentration (CHL) of important phytoplankton groups (PFT-CHL), the underwater light attenuation coefficients (Kd) for the ultraviolet (UV) and the blue spectral region separately (KdUV, KdBlue), and the sun-induced marine chlorophyll-a fluorescence signal (SIF-marine) from TROPOMI S5P level-1 data;
  4. explore the potential of the UV range of S5P for ocean biology;
  5. use complementary products from Sentinel-3 (S3) and S5P for exploring the UV measurements of TROPOMI for assessing sources of coloured dissolved organic matter (CDOM) and the amount of UV-absorbing pigments in the ocean;
  6. validate with established reference in situ datasets and perform intercomparison to other satellite OC data;
  7. define strategic actions for fostering a transition of the methods from research to operational activities;
  8. maximize the scientific return and benefits from the S5P mission for surface ocean research and services (e.g. CMEMS) by assessing the synergies with other satellite sensors, in particular explore the synergistic use of S5P and S3.
