SBAS for ENVISAT (beta)
IREA/CNR
The Small BAseline Subset (SBAS) is an Advanced InSAR technique which implements the Small BAseline Subset (SBAS) algorithm. It allows the generation of Earth’s surface deformation time series and, more generally, interferometric products.

ALES for ENVISAT FDR4ALT
Owner: Marcello Passaro – Deutsches Geodätisches Forschungsinstitut – Technical University of Munich
ALES (Adaptive Leading Edge Subwaveform) is a subwaveform retracker for open ocean and coastal zone altimetry applications. It adopts the Brown-Hayne functional form (which is the functional form for pulse-limited altimetry) on a selected portion of the waveform containing the leading edge of the signal, which is optimised for coastal applications while guaranteeing the quality of the estimations in the open ocean as well. A specific sea state bias correction is also computed and shall be used when correcting the estimated range to compute the sea surface height. It provides the capability to process ENVISAT FDR4ALT (Fundamental Data Records for Altimetry) products to produce ALES L2 NetCDF products.

ARD for ENVISAT MERIS FR
Owner: Progressive Systems
The Analysis Ready Data for MERIS FR service is used to produce ARD for large MERIS datasets through an orchestrator based on SNAP graphs and python scripts. The tool is able to automatically download MERIS products from the ESA dissemination service and to output a subset (whose geographical extension is passed as a parameter) collocated per pixel with respect to a master image (raster or re-projected onto a CRS). The produced dataset can be used for AI applications and multi-temporal analysis where each image needs to be georeferenced and comparable at the pixel level.
