ALT Two maps compare irrigation across the United States; darker blue shows a larger irrigated share, and hatching marks cropland.
ALT ESA quote card featuring polar climate scientist Ruth Mottram on satellite records and models tracking how ice sheets are changing.
ALT Lake water levels in 2025 expressed as anomalies compared with the 1995–2020 reference period. The selected 75 water bodies consist of 55% near-natural lakes, 12% regulated lakes and 33% reservoirs.
ALT Aerosol–liquid-cloud relationships stratified by aerosol layer height, obtained from climate-model simulations.
ALT Visualisation based on Global remote sensing merged multi-mission monthly gridded significant wave height, L4 product, version 1.1. New dataset available here: https://climate.esa.int/en/catalogue/315d8e013696420192f1ea1d9191ca9c/
ALT Panel discussion at the UK Earth Observation Conference, with three speakers seated on stage and one speaking at a lectern. A large screen displays an ESA Earth Explorers slide showing satellite missions around a globe.
ALT Preliminary regional climate indicator results
ALT High-level workflow for the Rapid Evaluation Framework (REF) combines quality-assured model output with a collection of observational reference data then initiates diagnostics and generation of tabular and graphical representations of a variety of metrics. The results are then published via an API for bespoke analysis and on an online dashboard for community use. Figure available at https://doi.org/10.5281/zenodo.15594501 (Hoffman et al., 2026)
ALT A large projection of Earth showing Africa, Europe and Asia, with climate data including “4.6 mm per decade” and “111 Gt/yr”. An audience is seated below the screen in the darkened Deep Space 8K.
ALT A speaker holding a microphone stands in front of an audience as a projection shows the Arctic region, sea ice and the text “Summer Sea Ice Extent” in Deep Space 8K.
ALT A speaker addresses an audience in front of a large projection of a mountain glacier. Colour-coded lines illustrate changes across the glacier.
ALT A projection shows an aerial view of a city partly covered by a large translucent ice cube. Text explains that the cube represents one year of ice loss, while an audience watches from below.
ALT Graphic showing a satellite image of the Laurentian Great Lakes with turquoise and green areas in the water, labelled “RESETlakes”. Below, two scatter plots compare satellite-derived and in situ chlorophyll-a measurements for the OC-CCI and Lakes-CCI products, illustrating differences in their accuracy and sensor-related bias.
ALT Overview of the training material notebooks in the CCI Toolbox training environment, which show the different climate datasets that can be worked with.
ALT ESA quote card with portrait of Marta Luffarelli describing SATACI as a shared space for cross-disciplinary collaboration.
ALT Projected decline in the forest carbon sink in a business-as-usual scenario. The forest carbon sink is defined as the sum of five components: net carbon stock change in AGC, BGC, HWPs, deadwood (including litter), and soils. (a) Forest carbon sink of the EU-27. (b) Forest carbon sink of the five biogeographical regions, normalized by forest area (in hectare of forests, haF) to facilitate comparison.
