Quantifying the impact of linear regression model in deriving bio-optical relationships: the implications on ocean carbon estimations

Recent research by ESA Living Planet Fellow Marco Bellacicco in the frame of project PHYSIOGLOB gives new insights on how the choice of the regression method influences the derived bio-optical relationships in optical and satellite oceanographic studies. The authors compare the results obtained with diverse regression methods on the same bio-optical data set and quantify …

Arctic bathymetry from Cryosat-2 altimetry

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 …

InSAR Short-Time-Series for Land Cover Classification

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, …

SENTINEL-5P+ INNOVATION

Prime company: ESA EOP-SDS initiative (IT)

The Sentinel-5p+ Innovation activity is motivated by potential novel scientific developments and applications that may emerge from the exploitation of the Copernicus Sentinel-5p mission data. This satellite mission is dedicated to the precise monitoring of the Earth’s atmosphere with a highlight on tropospheric composition. The Sentinel-5p spacecraft was launched in October 2017, where fills the …

Join U-TEP webinars and learn about resources to address urban environment and sustainability global issues

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), …

ARCTIC+ THEME 3 – FRESH WATER FLUXES (ArcFlux)

Prime company: Technical University of Denmark (DK)

The Arctic is a complex region encompassing different physical and biogeochemical processes and interactions among several components of the Earth system (e.g., sea ice, ocean, glaciers, ice caps, the Greenland Ice Sheet, snow, lakes and river ice, permafrost, vegetation, complex interactions with the atmosphere, people, etc.). Changes in the Arctic have a strong impact on …

The optical signature of intense subauroral ion drifts

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 …

SENTINEL-3 TANDEM FOR CLIMATE (S3TC)

Prime company: ACRI-ST S.A.S. (FR)

After 2 years in orbit, the Sentinel-3A satellite from the Copernicus program was joined by Sentinel-3B. During the first six months of the mission, the two satellites will fly in close formation. Sentinel-3A and Sentinel-3B observe the same place on the Earth within 30 seconds. This so-called tandem phase makes it possible to inter-calibrate very accurately the …

STSE-ARCTIC+ THEME 5 – CONTRIBUTIONS TO THE YEAR OF POLAR PREDICTIONS (YOPP)

Prime company: THE INVERSION LAB THOMAS KAMINSKI CONSULTING (DE)

The A+5 study belongs to the STSE ARCTIC+ cluster of projects and specifically contributes to the Year of Polar Prediction (YoPP). A+5 is constructing a flexible system for Arctic Mission Benefit Analysis (ArcMBA) that evaluates in a mathematically rigorous fashion the observational constraints imposed by individual and groups of EO (and in situ) data products …
