Sentinel-3

The Sentinel-3 mission is at the forefront of Earth observation, delivering a wealth of crucial information for scientists, environmentalists, and stakeholders alike. With its advanced optical imaging system, the Sentinel-3 satellite constellation captures data across an impressive range of 13 spectral bands, spanning from visible to infrared wavelengths. This comprehensive multi-spectral capability enables in-depth analysis of diverse Earth phenomena, such as monitoring changes in land cover, assessing vegetation health, examining coastal areas, and tracking inland water dynamics. By leveraging the rich and detailed data provided by Sentinel-3, users gain a deeper understanding of our planet's complex processes, paving the way for informed decision-making, sustainable resource management, and a better future for all.

Please note that Sentinel-3 marine data offered by EUMETSAT and provided on CDSE and CREODIAS are not aligned with the newest baseline provided by EUMETSAT.

Sentinel-3 Level-2 marine datasets/product types affected:

  • OLCI
    • OL_2_WFR
    • OL_2_WRR
  • SLSTR
    • SL_2_AOD
    • SL_2_FRP
    • SL_2_WST
  • SRAL
    • SR_2_WAT

We are currently analyzing the situation and working on replacing the archive with newly produced reprocessed baselines, to secure consistent processing baselines between reprocessed files and operational files.

EUMETSAT does not recommend using old baseline data, especially for long term observations.

In the meantime, following the recommendation from EUMETSAT, please use the newest data from EUMETSAT Data Store: https://data.eumetsat.int/

  • Instrument: Ocean and Land Colour Instrument (OLCI), Sea and Land Surface Temperature Radiometer (SLSTR), Synthetic Aperture Radar Altimeter (SRAL)
  • Resolution: Varies depending on the instrument and spectral band:
    1. OLCI: 300m (21 spectral bands), 1km (1 spectral band)
    2. SLSTR: 500m (visible and near-infrared spectral bands), 1km (thermal infrared spectral bands)
    3. SRAL: 300m (swath width)
  • Revisit time: Less than 24 hours for OLCI and SLSTR instruments, enabling frequent data acquisition and monitoring of rapidly changing conditions. SRAL data is acquired along the ground track, resulting in a global coverage every 28 days
