  • Celebrating ESA’s first small satellite with science success

    Scientists and data users gathered at a special workshop to celebrate the end of PROBA-1’s CHRIS sensor and discuss the results of this overachieving mission.

  • How to find the geographical and temporal coverage of the ESA TPM archive collections

    Explore the ESA TPM archive collections, containing Earth Observation data from international partners, and learn how to discover their geographical and temporal coverage for research and pre-operational applications.

  • What are the Terms of Applicability?

    Essential information about data ordering, accessibility conditions, and distribution constraints for TPM EO data.

  • Workshop celebrates end of long-running PROBA-1 satellite

    In January, ESA will mark the end of its long-running CHRIS sensor onboard the PROBA-1 satellite in a special workshop.

  • New cross-calibration readies PROBA-1 data for climate research

    While PROBA-1 has already exceeded expectations by suppling over 21 years of Earth observation hyperspectral data, recent cross-calibration activities are aiming to ensure the data will robustly serve long time-series research, even when the satellite ends operations.

  • PROBA-1 - End of CHRIS acquisitions

    The CHRIS instrument onboard PROBA-1 successfully ended its operational phase in December 2022 and will no longer acquire images.

  • Global understanding of Earth's land surfaces greatly boosted by satellite data

    ESA perform land surface monitoring with a range of instruments onboard satellites acquiring optical and radar data. Collections of data from these missions are freely available for research purposes.

  • A summary of ESA Third Party Mission collections

    A new summary is available, showcasing the ESA archives for Third Party Mission collections.

  • Space helps monitor Earth’s changing biosphere

    Earth’s biosphere is continually changing. Through its pioneering Earth observation missions, ESA is making critical contributions to monitor these changes and their impacts on Earth’s water and carbon cycles.

  • PROBA-1 - From technology demonstration to long-term Earth observation

    Learn about ESA's PROBA-1 (Project for On-Board Autonomy) mission in our new infographic.

  • A long way for a little satellite

    The PROBA-1 satellite, a technology demonstrator later turned into an Earth observation mission – and just a cubic metre in volume – is reaching 20 years of continuity, making it a huge success.

  • PROBA-1 HRC

    The HRC Level 1A product is an image with a pixel resolution of 8m. The data are grey scale images, an image contains 1026 x 1026 pixels and covers an area of 25 km2. HRC data is supplied in BMP format. All PROBA-1 passes are systematically acquired according to the current acquisition plan, HRC data are processed every day to Level 1A and made available to ESA users. Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.

  • PROBA-1 CHRIS Level 1A

    CHRIS acquired a set of up to five images of each target during each acquisition sequence, these images were acquired when PROBA-1 was pointing at distinct angles with respect to the target. CHRIS Level 1A products (supplied in HDF data files, version 4.1r3) include five formal CHRIS imaging modes, classified as modes 1 to 5: Mode Name Swath Spectral Bands/Ground Resolution Mode 1 Aerosols 13 km 62 at 34 m (773 nm / 1036 nm) Mode 2 Water bands 13 km 18 at 18 m Mode 3 Land channels 13 km 18 at 18 m Mode 4 Chlorophyll band set 13 km 18 at 18 m Mode 5 Land channels 6.5 km 37 at 18 m Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.

  • How do I access the ESA Third Party Mission (TPM) data?

    Access ESA Third Party Mission (TPM) data by applying with 'Fast Registration with Immediate Access' or 'Fast Registration with Approval.

  • What is the ESA online On-The-Fly dissemination service?

    Explore ESA's On-The-Fly dissemination service (L-OADS), featuring Third Party Missions and ESAR products enabling immediate downloads upon request with a valid EO Sign-In account.
