  • 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.

  • Space and the Arctic 2009 Workshop

    Temperatures in the Arctic are rising at an unprecedented rate. This workshop looked at the needs and challenges of working and living in the rapidly changing Arctic and explore how space-based services might help to meet those needs.

  • 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.

  • SEASAR 2006

    ESA organised it's first SAR oceanography workshop, SEASAR 2006, entitled "Advances in SAR Oceanography from Envisat and ERS missions"

  • SCIRoCCo

    The SCIRoCCo project is an interdisciplinary cooperation of scatterometry experts aimed at promoting the continuing exploitation of ESA's unique 20 years' worth of ERS Scatterometer data.

  • Satellites investigate Earth’s terrestrial hydrosphere

    ESA’s Earth observation satellites are playing a leading role in furthering our understanding of how Earth’s water cycle is being influenced by humankind.

  • Satellite Radar Altimetry: past and future

    Satellite radar altimetry measurements yield a wealth of information that can be used for a wide range of applications.

  • Polar TEP

    The Polar Thematic Exploitation Platform (TEP) enables access, processing, uploading, visualisation, manipulation and comparison of data over the polar regions.

  • Oil Spill in Oporto (Portugal), October 1994

    See the oil spill near Oporto's coast captured in an ERS satellite image.

  • Monitoring water on Earth's surface

    ESA's Earth observation satellites are playing a leading role in furthering our understanding of how Earth's terrestrial hydrosphere is being influenced by humankind.

    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.

  • Introducing Mirko Albani

  • International Charter Space and Major Disasters

    Learn about the International Charter Space and Major Disasters, which ESA participate in disaster monitoring.

  • 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.
