  • Showcasing ESA's HEDAVI Earth observation tool

    ESA's HEDAVI (HEritage DAta VIsualiation) is a platform that allows users to freely access over 40 years of ESA Earth observation Heritage, Third Party Missions and some Copernicus data.

  • Interview with Mirko Albani

    ESA’s Heritage Space Programme Manager discusses the programme's objectives and challenges.

  • Kansai and Kobe International Airports (Osaka Bay, Japan)

    View satellite images detailing the construction and development of Kansai International Airport, from its early stages in 1978 to completion in 2009.

  • Celebrating 20 years of ERS

    Discover the evolution of Earth observation technology through satellite images of Rome captured by ERS-1 and ERS-2 over a span of 20 years.

  • Flood,Tuscany (Italy), October 1992

    Explore the 1992 floods in Florence, Italy, through this ERS multi-temporal satellite image.

  • 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.

  • ESA's improved Earth system data records: what is in store for the future?

    Fundamental Data Records (FDRs) are instrumental in advancing our understanding of Earth systems and for addressing societal challenges effectively. These long-term records contain uncertainty-quantified, calibrated and geo-located multi-instrument/multi-platform satellite sensor data spanning several decades to support climate-related applications.

  • Showcasing success stories from ESA's Heritage Missions

    Find out how ESA's Heritage Space Programme data continue to help, even decades after they finished operations, in our latest infographic.

  • FDR4ALT - ESA unveils new cutting-edge ERS/Envisat Altimeter and Microwave Radiometer Datasets

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

  • Fundamental Data Records for Radiometry [MWR_FDR___]

    This dataset is a Fundamental Data Record (FDR) resulting from the ESA FDR4ALT project. The Fundamental Data Record for Radiometry V1 products contain intercalibrated Top of the Atmosphere brightness temperatures at 23.8 and 36.5 GHz. The collection covers data for the ERS-1, ERS-2 and Envisat missions, and is built upon a new processing of Level 0 data, incorporating numerous improvements in terms of algorithms, flagging procedures, and corrections. Compared to existing datasets, the Radiometry FDR demonstrates notable improvements in several aspects: New solutions for instrumental effects (ERS Reflector loss, Skyhorn, and Sidelobe corrections) Native sampling rate of 7Hz with enhanced coverage 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.

  • 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.

  • Cloud-free collections key for land monitoring

    Satellite imagery is a crucially important tool for monitoring the land, but cloud cover can often block parts of Earth’s surface from view, limiting subsequent analyses.

  • 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.

  • How satellite data help to shape society

    Data from ESA’s Earth observation archives are improving understanding of the interactions between human activities and the environment, helping to power green economic development and boosting prosperity in Europe and beyond.

  • Heritage data trains neural networks to detect urban sprawl

    Using data from non-operational ESA remote sensing missions, researchers have trained a network of artificial neurons to recognise how cities change over decades. They hope this will help city planners reduce the impact that urbanisation has on the environment.

  • 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.

  • Data preservation takes centre stage at Living Planet Symposium

    Against the backdrop of the famed Rhine River, world-class scientists and Earth observation data-users are gathered this week in the historical city of Bonn, at the Living Planet Symposium (LPS).

  • 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.

  • ERS Heritage Data allow for 30 years of science

    At their time of launch thirty years ago, the two ERS satellites were the most sophisticated Earth observation spacecraft ever developed and launched by Europe.

  • ERS - ESA’s first Earth observation satellites

    To mark the 30th anniversary of ERS, we've released a new infographic summarising the mission.
