  • Updated Precise Orbit data (POD) for the full ERS-1 and ERS-2 mission available

    The Precise Orbit files (ERS.ORB.POD) for the entire ERS-1 and ERS-2 mission periods have been reprocessed with up-to-date standards.

  • Transforming space data into climate action

    ESA’s Earth observation activities are playing a key role in the revitalised global drive to combat climate change.

  • Trailblazing ERS-2 mission enables climate change applications

    As ESA’s ERS-2 satellite approaches Earth’s atmosphere for reentry, it’s time to reflect on the mission’s great achievements in powering climate-related applications.

  • Showcasing Fundamental Data Records for Altimetry

    ESA has developed a comprehensive suite of Earth system data records as part of the Fundamental Data Records for Altimetry (FDR4ALT) project.

  • SEOM CAWA

    The Advanced Clouds, Aerosols and WAter vapour products for Sentinel-3/OLCI project aims to develop and improve the advanced atmospheric retrieval algorithms developed for MERIS and OLCI instruments.

  • SEASAR 2006

    Learn about the 2022 edition of ESA's Living Planet Symposium.

  • Living Planet Symposium 2019

    ESA's Living Planet Symposia are amongst the biggest Earth observation conferences in the world. Scientists present their latest findings on Earth's environment and climate.

  • Land Ice Thematic Data Product [ALT_TDP_LI]

    This is the Land Ice Thematic Data Product (TDP) V1 resulting from the ESA FDR4ALT project and containing estimates of ice sheet surface elevation and associated uncertainties. The collection covers data for three different missions: ERS-1, ERS-2 and Envisat, and based on Level 1 data coming from previous reprocessing (ERS REAPER and the Envisat V3.0) but taking into account the improvements made at Level 0/Level 1 in the frame of FDR4ALT (ALT FDR). The Land Ice TDP focuses specifically on the ice sheets of Greenland and Antarctica, providing these data in different files. For many aspects, the Land Ice Level 2 and Level 2+ processing is very innovative: Improved relocation approach correcting for topographic effects within the beam footprint to identify the Point of Closest Approach Homogeneous timeseries of surface elevation measurements at regular along-track reference nodes. The FDR4ALT products are available in NetCDF format. Free standard tools for reading NetCDF data can be used. Information for expert altimetry users is also available in a dedicated NetCDF group within the products. Please consult the FDR4ALT Product User Guide before using the data. The FDR4ALT datasets represent the new reference data for the ERS/Envisat altimetry missions, superseding any previous mission data. Users are strongly encouraged to make use of these datasets for optimal results.

  • Interviewing Mirko Albani

    ESA’s Heritage Space Programme Manager describes the goals of the programme, some of the challenges involved in preserving and improving 40 years of historical Earth observation data, and his passion for curating this long-term archive.

  • Inland Waters Thematic Data Product [ALT_TDP_IW]

    This is the Inland Waters Thematic Data Product (TDP) V1 resulting from the ESA FDR4ALT project and containing improved Water Surface Height (WSH) data record from the ERS-1, ERS-2 and Envisat missions estimated using the ICE1 retracking range for its better performance on the hydro targets. The FDR4ALT products are available in NetCDF format. Free standard tools for reading NetCDF data can be used. Information for expert altimetry users is also available in a dedicated NetCDF group within the products. Please consult the FDR4ALT Product User Guide before using the data. The FDR4ALT datasets represent the new reference data for the ERS/Envisat altimetry missions, superseding any previous mission data. Users are strongly encouraged to make use of these datasets for optimal results.
