  • Rome supersite helps validate atmospheric space data

    In the sprawling, urban area of Rome, where atmospheric composition is impacted by complex coastal weather and pollution, ESA supports a powerful observatory spread across several locations.

  • International collaboration: Summarising ESA’s Third Party Missions

    ESA’s Third Party Missions programme consists of more than 50 missions from around the world. Learn more about the Third Party Missions in this video.

  • Timeline to over 40 years of historical satellite missions

    ESA's Heritage Space Programme preserves historical data from over 40 years of Earth observation missions.

  • An overview of ESA's Third Party Missions programme

    ESA’s Third Party Missions programme consists of almost 50 satellite missions, which are owned by organisations around the world. ESA has agreements with these organisations to acquire, process, and distribute data from their missions

  • ESA Third Party Missions timeline

    We've released a new timeline to illustrate the history of the ESA Third Party Missions.

  • Landsat MSS ESA Archive

    This dataset contains all the Landsat 1 to Landsat 5 Multi Spectral Scanner (MSS) high-quality ortho-rectified Level 1 GEO and GTC dataset acquired by ESA over the Fucino, Kiruna (active from April to September only) and Maspalomas (on campaign basis) visibility masks. The acquired Landsat MSS scene covers approximately 183 x 172.8 km. A standard full scene is nominally centred on the intersection between a path and row (the actual image centre can vary by up to 200 m). The altitude changed from 917 km to 705 km and therefore two World Reference Systems (WRS) were used. A full image is composed of 3460 pixels x 2880 lines with a pixel size of 60 m. Two different product levels are available: Geometrically and terrain corrected GTC Products (L1T): The most accurate level of processing as they incorporate Ground Control Points (GCPs) and a Digital Elevation Model (DEM) to provide systematic geometric and topographic accuracy; with geodetic accuracy dependent on the number, spatial distribution and accuracy of the GCPs over the scene extent, and the resolution of the DEM used. Geometrically corrected GEO Product (L1G): Normally generated where there is a lack of GCPs, and are derived purely from data collected by the sensor and spacecraft e.g. ephemeris data.

  • New life for Landsat historical data

    45 years of data, more than 1.8 million images, these are the numbers of an adventure started 48 years ago with the launch of the first Landsat satellite.

  • Aura OMI complete NASA dataset

    The OMI observations provide the following capabilities and features: A mapping of ozone columns at 13 km x 24 km and profiles at 13 km x 48 km A measurement of key air quality components: NO2, SO2, BrO, HCHO, and aerosol The ability to distinguish between aerosol types, such as smoke, dust and sulfates The ability to measure aerosol absorption capacity in terms of aerosol absorption optical depth or single scattering albedo A measurement of cloud pressure and coverage A mapping of the global distribution and trends in UV-B radiation. The OMI data are available in the following four levels: Level 0, Level 1B, Level 2, and Level 3. Level 0 products are raw sensor counts. Level 0 data are packaged into two-hour "chunks" of observations in the life of the spacecraft (and the OMI aboard it) irrespective of orbital boundaries. They contain orbital swath data. Level 1B processing takes Level 0 data and calibrates, geo-locates and packages the data into orbits. They contain orbital swath data. Level 2 products contain orbital swath data. Level 3 products contain global data that are composited over time (daily or monthly) or over space for small equal angle (latitude longitude) grids covering the whole globe.

  • EDAP

    The ESA Earthnet Data Assessment Pilot (EDAP) project will perform assessments for various missions to ensure the delivered data is fit for purpose.

  • SLAP

    The SLAP (Systematic Landsat Archive Processing) project covers the MSS, TM and ETM+ products from Landsat missions 1 – 7, and is the first systematic reprocessing of the ESA Landsat archive.

  • LANDSAT_Products_Description_Document.pdf

    This document acts as a User Guide to the Landsat MSS, TM and ETM+ archives, focussing more specifically on the Landsat TM and ETM+ products from the Kiruna, Maspalomas and Matera archives (including from the Matera, Fucino, Neustralitz, O’Higgins, Malindi, Libreville and Bishkek ground stations) that have been generated as part of the ESA archive bulk-reprocessing project.
