The year 2025 served as a period for European Earth Observation (EO), marked by advancements in atmospheric monitoring and the scaling of retrieval capabilities. At the center of this progress, GRASP Earth navigated a year of operational and scientific activity. The landscape of European space infrastructure was altered by the launch and commissioning of the Copernicus Sentinel-4 and Metop-SG 3MI missions. These atmospheric monitoring systems are currently delivering GRASP-processed aerosol and surface products to the scientific community, providing data for climate and air quality research.
This operational activity was accompanied by a portfolio of research and strategic initiatives. The initiation of several European projects has supported the development of synergetic EO Level-2 data, while milestones reached across the project portfolio have defined the direction of the group. These technical contributions were acknowledged through various institutional awards and industry labels. Furthermore, the year included the publication of peer-reviewed research regarding the algorithm’s capabilities in areas such as multi-mission synergetic retrieval and diurnal properties from geostationary data.
