DESCRIPTION:Destination Earth (DestinE) is a flagship initiative led by the
  European Commission\, implemented by the European Organisation for the Ex
 ploitation of Meteorological Satellites (EUMETSAT)\, the European Space Ag
 ency (ESA) and the European Centre for Medium-Range Weather Forecasts (ECM
 WF). It aims to create highly detailed Digital Twins (DTs) of the Earth\, 
 enabling precise simulations for a variety of uses. Currently\, the initia
 tive focuses on two primary Digital Twins:  the Weather Extremes Digital T
 win (ExtremeDT) and the Climate Change Adaptation Digital Twin (ClimateDT)
 . Over the coming years\, the scope of Digital Twins is set to expand\, ne
 cessitating improved access to data and streamlined methods for working wi
 th it. This is where the Destination Earth Data Lake (DEDL) plays a pivota
 l role\, offering comprehensive data discovery\, access\, and processing s
 ervices tailored to the needs of DestinE users.\n\nThe DEDL operates on tw
 o key levels: ‘Data Discovery and Access’ and ‘Edge Services’. DED
 L Discovery and Data Access services is provided by Harmonized Data Access
  (HDA) tool which provides a single\, federated entry point to the service
 s and data\, including resources from existing datasets and complementary 
 sources such as in-situ and socio-economic data. Notably\, it also provide
 s access to the unique datasets generated by DestinE’s Digital Twins. By
  combining these sources\, users can seamlessly explore\, integrate\, and 
 analyze both existing services and the innovative data produced by the Dig
 ital Twins. What is more\, all this data is provided as a full archive imm
 ediately available to the user. The services rely on use of the SpatioTemp
 oral Asset Catalogs (STAC) standard which means:\n\n•	The search in the 
 dataset is done according to the STAC protocol\;\n•	The Federated Catalo
 g search proxy component converts STAC queries into queries adapted to the
  underlying catalog and returns the results to the user in STAC format\;\n
 •	The services are presented in service catalog.\n\nEdge Services offere
 d by DEDL provides:\n•	Cloud Computing\n•	STACK Application Developmen
 t Environment\n•	Hook Services\n\nThe cloud computing service is powered
  by the ISLET infrastructure\, a distributed Infrastructure as a Service (
 IaaS) built on OpenStack\, using the Horizon interface. It allows users to
  manage virtual machines\, s3 storage\, and run advanced computations via 
 a graphical user interface (GUI) or command-line interface (CLI). For more
  complex tasks\, Kubernetes integration is available. A standout feature o
 f ISLET is its proximity to data sources\, operating near High-Performance
  Computing (HPC) facilities. This is achieved through data bridges\, enabl
 ing efficient processing of large datasets\, including those from Digital 
 Twins\, in conjunction with HPC systems.\n\nThe STACK environment supports
  application development using JupyterHub and DASK\, with Python\, and R l
 anguages. Users can create DASK clusters on selected infrastructure or clo
 ud sites to process data directly where it resides\, removing the need for
  extensive local setup and optimization.\n\nHook Services is a set of pre-
 defined workflows which could be used by users as a ready-to-use processor
 s\, e. g. : Sentinel-2: MAJA Atmospheric Correction\; \, Sentinel-2: SNAP-
 Biophysical\; Sentinel-1: Terrain-corrected backscatter. It also enables w
 orkflow functions to generate on-demand higher-level products\, such as te
 mporal composites.\n\nThe DestinE Data Lake is a transformative initiative
  that revolutionizes how Earth Observation data is managed and utilized. B
 y integrating innovative infrastructure (ISLET)\, data services (HDA)\, re
 liable processors (Hook Services)\, and user-friendly development tools (S
 TACK)\, DEDL enables unprecedented levels of data harmonization\, federati
 on\, and processing. Moreover\, the DEDL plays a crucial role in empowerin
 g DestinE users by providing them with seamless access to vast datasets an
 d advanced computational tools. It simplifies the process of data explorat
 ion\, integration\, and analysis\, enabling researchers\, policymakers\, a
 nd developers to focus on innovation and decision-making rather than techn
 ical barriers. By offering a comprehensive suite of services designed to w
 ork close to the data\, DEDL ensures that users can efficiently utilize th
 e wealth of information generated by the Digital Twins and maximize the im
 pact of their work. This cutting-edge system enhances climate research cap
 abilities and supports sustainable development efforts on a scale previous
 ly unattainable.
