The goal of this project is to further develop and validate a high frequency SAR interferometric phase center (DSM) approach together with existing and forthcoming DTMs to map forest biomass (AGBD). To that end, the study will: 1) develop a novel method for annual AGBD mapping with individual TanDEM-X DSMs and Sentinel-1 time series for …
The project aims to maximise the use of Earth observation data to understand the impact of the Arctic freshwater export and Greenland ice discharge on modulating the water column structure and phytoplankton dynamics on the East Greenland Shelf. This will include a dedicated effort in mapping and quantifying three important components of the Arctic marine …
Development of a novel methodology capable of mapping the Belowground Biomass Density (BGBD), Litter Biomass Density (LBD), and Shrub Biomass Density (SBD) combining Earth Observation (EO) data from the Sentinel and ALOS-2/PALSAR-2 missions. Large-scale mapping of these biomass pools is still not done, unlike the Aboveground Biomass Density (AGBD), since it usually relies in Airborne …
Aim This project aims to provide a comprehensive, long-term analysis of fuel characteristics to understand the role of vegetation in controlling the changing trends of fire activity on the planet. To achieve this goal, Fuelity will leverage the extensive information available from ESA-funded missions that have improved biomass estimations. It will also complement several other …
Vegetation is a central component of the Earth’s system, governing surface water exchanges and constituting one of the largest terrestrial carbon reservoirs. Ongoing disturbances, whether natural or human-induced, combined with the impacts of changing climate, induce rapid alterations on a global scale. Accurate and consistent assessments of vegetation status are imperative to meet the needs …
During drought, water deficit depletes tree water content, which can lead to water stress mortality, vulnerability to wildfires and increased susceptibility to insect and pathogen attacks. Widespread tree mortality could be triggered by increased drought frequency, such as expected in Europe, which can lead to disrupting the provision of important ecosystem services and increased carbon …
Fostering Advancements in Foundation Models via Unsupervised and Self-Supervised Learning for Downstream Tasks in Earth ObservationThe objectives will be achieved through the validation of the proposed FMs (Multimodal Foundation Models) on suitable downstream applications that address global societal challenges. More specifically, the validation of the proposed FM architectures will be conducted on six main use …
Background The European Space Agency is organising the 11th International Workshop on Science and Applications of SAR Polarimetry and Polarimetric Interferometry, PolInSAR & Biomass. The workshop will be held at Espaces Vanel Toulouse, France on the following dates: 11th PolInSAR & Biomass Workshop: 19 – 23 June 2023 The event will be preceded by the 7th ESA Advanced Course …
The BiomAP project aims to Integrate active and passive microwave data towards a novel global record of aboveground biomass maps. This comprises an end-to-end assessment of active and passive microwave observations at coarse spatial resolution at the longest wavelengths available in space to generate global AGB estimates. This work will eventually provide a 5-years baseline, …
POSEIDON aims to understand the response of ocean ecosystems to climate warming and extreme events (e.g., marine heatwaves). Long-term trends (> 23 years) in phytoplankton ecological indicators (biomass, size structure and phenology) will be analysed in different regions, encompassing a range of conditions found in the global oceans. POSEIDON will further investigate the spatiotemporal variability …
