Data Fusion (DInSAR & GNSS)

Data fusion techniques allow to obtain ground displacement maps with high resolution and precision. While DInSAR results shows the displacement in the Line of Sight (LOS) vector, we can obtain multiple LOS values from different acquisition geometries from the same or different satellites and combine it with low density but very precise techniques like GNSS to be able to obtain high density 3D maps.

Other data, like optical or ground based techniques, can be ingested in the data fusion algorithm and processed with a very low computational cost.

Advanced fusion methods


Different variables in oceanography and in other contexts share structural information (singularity exponents). Therefore, we can use information from one variable to improve the quality of another variable.

This approach has been successfully applied in many projects (EO4SIBS, SO FRESH, MINKE, CRICES) and now is extended to marine debris.

Estimation of vegetation biophysical variables and land surface phenology

+40 years of consistent and global time series of leaf area index, fraction of absorbed PAR and vegetation cover are estimated from optical satellite data. This datasets are used for analysing trends and anomalies in vegetation, retrieval of land surface phenology and modelling vegetation-climate dynamics.

Simulating complex ecosystems using radiative transfer models


Spectral properties of the complex ecosystems with different vegetation layers such as open forest, vineyards, orchards, can be accurately characterized by combining leaf, 2D and 3D radiative transfer models. Vegetation phenology of the different layers can also be characterized and modeled. These physically based models can be used to derive morphological and biochemical plant traits by model inversion.


Reconstruction of HR sea surface velocities

Exploiting known synergies among different ocean variables, the velocity field can be reconstructed at high-resolution using information from Sea Surface Temperature and combining it with altimetry information.

Tracking pollutant dispersion on the sea


Using Lagrangian descriptors, the presence of ocean transport barriers can be evidenced. This helps in the tasks of risk mitigation and incident management, and has also application in other domains like fisheries.
