7 years of CryoSat-2, jointly with other satellite altimetry data allowed scientists from DTU Space to develop an altimetric gravity model and exploit it to derive the first ever Arctic bathymetry map predicted from marine gravity. This has been combined with the existing IBCAO bathymetry map (derived from sparse ship soundings) to create a new …
Interferometric (InSAR) short-time-series of Sentinel-1 SAR data acquired over central Europe were exploited in a new approach for the generation of large-scale thematic maps. Temporal features, extracted from the evolution of the interferometric coherence, together with backscatter, were used as input for a machine learning-based classifier. Three land cover classes were extracted: artificial surfaces, forests, …
A series of violent and harmful explosions occurred on 3 July afternoon at Stromboli volcano, causing one dead. Glowing hot bombs and lapilli were ejected from all over the summit area and produced an eruption column that rose approx. 3-5 km. A series of fires were caused by the hot debris falling back in the …
Decision-makers, planners and scientists can easily find in the Urban Thematic Exploitation Platform (U-TEP) resources, including multi-source data and visualisation/analytics tools, that help them creating and maintaining sustainable urban environments in major cities but also in smaller, rural areas. One of the recent add-ons to the rich database is the World Settlement Footprint 2015 (WSF-2015), …
New research published in Geophysical Research Letters investigates in-situ ionospheric plasma measurements from the European Space Agency’s Swarm satellites coincident with ground-based optical measurements of the phenomenon known as “Steve”. The authors show that Steve is consistently associated with narrow ionospheric flow channels called subauroral ion drifts (SAID). These observations are unusually intense with faster …
Applying a novel analytical theory, scientists have a fast new way of retrieving snow grain size – and albedo – from Sentinel-3 data. Read more about the importance of snow grain size and the results obtained in the Pre-Operational Sentinel-3 snow and ice products (SICE) project in ESA EO portal featured story.
Ice is without doubt one of the first casualties of climate change, but the effects of our warming world are not only limited to ice melting on Earth’s surface. Ground that has been frozen for thousands of years is also thawing, adding to the climate crisis and causing immediate problems for local communities. Read the …
Follow the links and find out about the importance of studying the whole water cycle and how this has been tackled in the Mediterranean within a recently published paper presented at the Living Planet Symposium.
We are realising the new global model of Earth’s lithosphere and upper mantle by combining gravity anomalies, geoid height and gravity gradients complemented with seismic, thermal and rock information
Experiments show that SMOS can help improve errors in extreme events forecast lead times by 36–72 hours in the extratropics.
