  • How SMOS could help conserve prehistoric cave art

    Paintings etched by our distant ancestors onto walls deep within the Altamira caves in Northern Spain provide an invaluable glimpse into the earliest throws of human culture – and, as a result, the ongoing preservation of these ancient artworks is of crucial importance to those tasked with conserving the prehistoric site.

  • HydroGNSS

    HydroGNSS is a microsatellite mission, which is part of the Scout framework, and consists of a GNSS-R (Global Navigation Satellite System Reflectometry) constellation that primarily addresses land. Scout missions are a new element in ESA's Earth Observation FutureEO Programme.

  • Workshop demonstrates benefits of soil moisture data validation tool

    Soil moisture scientists had the opportunity to train with an ESA validation service at a recent workshop. The tool, which is highly rated by the CEOS Working Group on Calibration and Validation, provides valuable support for validating data.

  • Featuring the power of Earth observation data at EGU

    The European Geosciences Union General Assembly 2024 brings together geoscientists from all over the world, aiming to provide a forum where scientists and early career researchers can present their work and discuss their ideas with experts, in all fields of geoscience.

  • Announcement of Opportunity for SAOCOM – deadline extended

    The submission deadline for the ESA/CONAE Announcement of Opportunity for SAOCOM mission data has been extended until 31 December 2024.

  • 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.

    This report summarises the FLEXSense 2019 campaign.

  • FLEXSense 2019

    The FLEXSense 2019 campaign activities were undertaken in Germany and Italy with the goal of providing a complete set of high-resolution experimental data, including all relevant elements required for the preparation of the FLEX satellite mission.

  • Ensuring soil moisture data quality with reference measurements

    ESA is taking steps to verify the accuracy of soil moisture estimation with the Fiducial Reference Measurements for Soil Moisture (FRM4SM) project and a new version of the Quality Assurance for Soil Moisture (QA4SM) service.

  • Update for the SMOS Near Real Time Sea Surface Wind Speed Processor configuration

    An updated configuration of the SMOS Near Real Time Sea Surface Wind Speed Processor was deployed at the IFREMER and ESA operational ground segment on 4th December 2023.

  • New version v206 of the SMOS-CryoSat level 4 sea ice thickness product is now available

    The new version 206 of the merged SMOS-CryoSat level 4 sea ice thickness product is now available on the SMOS data dissemination service.

  • Experimental version of SMOS Antarctic Sea ice thickness product is now available

    The experimental version of SMOS Antarctic Sea ice thickness product was produced using a method to derive the sea-ice thickness from 1.4 GHz brightness temperatures previously developed for the Arctic, with only modified auxiliary data. The product is available in the cold season during the freezing period, typically March to October for the Southern Hemisphere.
