<p>As a result of a recommendation at the Atmospheric Composition Validation and Evolution workshop held on 13-15 March 2013, representatives from the atmospheric composition and optical Level 1 communities participated in a meeting in June 2013 to discuss how to integrate the latest findings on Level 1 activities into the upcoming reprocessing campaigns of ERS1/ERS-2/Envisat and to support scientific research, the EO applications and exploitation community, ESA programmes, to prepare for the Sentinels operations phase and draw together lessons learned for future missions.</p>

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.

Rome supersite helps validate atmospheric space data

Measuring glacier mass changes from space is more accurate and comprehensive thanks to the CryoTEMPO-EOLIS CryoSat swath data products, which now cover glaciers worldwide.

Global glacier mass change data now available from CryoSat

A software maintenance has been scheduled on Tuesday, 26 September 2023 from 08:00 to 14:00 UTC.

ESA EO Services - maintenance on 26 September 2023

Previously, quality checks of the Ice Baseline-E reprocessing products observed a discrepancy in the metadata of products with incremented version numbers (E002, E003).

CryoSat Ice Baseline-E Reprocessed Data - Update

A maintenance activity is scheduled for several EO websites on 22 September.
