Throughout 2025, the CEOS-ARD Oversight Group undertook a comprehensive consultation effort to gather feedback on what the Earth observation community would value in the next phase of CEOS-ARD. This feedback formed the basis of the Future of CEOS-ARD – Consultation Paper and Concept Note endorsed by CEOS Principals at the 39th CEOS Plenary in November […]

Spaceborne hyperspectral sensors provide contiguous spectral coverage of the Earth’s surface within the optical and infrared spectrum, enabling the derivation of several biogeophysical products and user applications. Atmospheric correction (AC) is essential for processing satellite data because it removes the effects of the atmosphere (e.g., aerosols, water vapor and dust) that alter the signal before […]

  The CEOS Analysis Ready Data (CEOS-ARD) Product Family Specifications (PFS) are a suite of documents that detail minimum requirements for ‘analysis ready’ satellite Earth observation data across various domains. Ensuring datasets are compliant with the CEOS-ARD PFS means they should be more suited to immediate analysis by more users with a minimum of additional […]

The third edition of the CEOS-ARD Newsletter has been published! Read about new datasets and specifications, as well as multi-modal applications of CEOS-ARD.  

Two new CEOS Analysis Ready Data (CEOS-ARD) Product Family Specifications (PFS) have recently been endorsed: Nighttime Lights Surface Radiance & Ocean Radar Backscatter. This brings the total number of PFS to seven, covering both optical and radar products and across land and oceans. Ocean Radar Backscatter (ORB) The Ocean Radar Backscatter (ORB) PFS is derived […]

The second edition of the CEOS-ARD Newsletter has been published! Read about the highlights of CEOS-ARD at ESA’s Living Planet Symposium, held 23-27 May, 2022.  

The first edition of the CEOS-ARD Newsletter has been published! Read about the new Aquatic Reflectance PFS, new CEOS-ARD products Sentinel-2 and EnMAP, and how CEOS-ARD is helping to power Digital Earth Africa.  

Note: Version 2.0 of the CEOS-ARD Aquatic Reflectance PFS is now available as of June 2025! View the updated PFS here or read more at ceos.org/ard. On 23 February 2022, CEOS’s Land Surface Imaging Virtual Constellation (LSI-VC) endorsed a new Analysis Ready Data (ARD) Product Family Specification (PFS) for Aquatic Reflectance (AR) products. Following the […]

The CEOS Working Group on Calibration and Validation (WGCV) has concluded their assessment of ESA’s Sentinel-2 Level-2A and DLR’s EnMAP Surface Reflectance (SR) products, finding that both are CEOS ARD compliant at the Threshold level. CEOS Analysis Ready Data (ARD) are satellite data that have been processed to a minimum set of requirements and organized […]
