2024 has been a year of incredible Earth observation moments — spanning launches, mission milestones and innovative research, from data users around the world.

2024 highlights: Showcasing key Earth observation stories

Held between 2 and 6 December 2024, at ESA’s Earth Observation centre in Frascati, Italy, the fifth edition of ESA’s Very High-Resolution Radar & Optical Data Assessment workshop reached new levels of success.

Due to an issue registered on the VFM (Vector Field Magnetometer) on board Swarm Alpha, several gaps have been identified in the VFM science data from 7 December at 14:33 UTC to 10 December at 12:11 UTC.

Data

The goal of RA calibration and validation activities was to verify the accuracy and quality of data the instrument acquired.

The Explorer mode of the HEritage DAta VIsualisation tool (HEDAVI) allows users to process on-the-fly, visualise, share and export Earth observation data from ESA’s Heritage and Third Party Missions.

In addition to releasing new datasets for Envisat SCIAMACHY, the European Space Agency (ESA) has advanced the earth observation capabilities by developing an experimental product under the ESA FDR4ATMOS project (Fundamental Data Records in the domain of satellite Atmospheric Composition).

Two new stories are now available in ESA’s HEDAVI (HEritage DAta VIsualisation) tool. HEDAVI visualises Earth observation data from satellites in ESA’s Heritage and Third Party Missions programme, and includes some data from the Copernicus Sentinel satellites.

New stories on change detection and ERS-2 re-entry in HEDAVI

The Discover mode in HEDAVI showcases the usefulness of Earth Observation (EO) data in a variety of applications through a list of case-studies—so-called “stories”. The first new feature allows users to share links to the stories in HEDAVI. The second new feature allows them to export any image of a case-study from the Discover mode to the Explorer mode.
