User can select here the size of the radar receiving window: 128 range bins (standard) or 128XN range bins (extended N times). 128X4 range bins (Extension by factor of 4) 128X3 range bins (Extension by factor of 3) 128X2 range bins (Extension by factor of 2) Zero-Padding is indicated for coastal zone and sea-ice analysis User can decide here whether to operate the Zero-Padding prior to the range FFT (section 4.8 in REF1). User can decide here whether to operate an exact Beam-Forming or an approximated Beam-Forming (more info at REF1) The processor prototype is versatile in the sense that the users can customize and adapt the processing, according their specific requirements, setting a list of configurable options. List of option entries in the G-POD graphic interface The on line SAR service is available here. You find more information about how to use the generic G-POD graphic interface at the G-POD wiki page available here. After the task submission, it is possible to follow, in real time, the status of the processing task. Using the G-POD graphic interface, it is possible to easily select the geographical area of interest along with the time of interest. These output data products are generated in standard NetCDF format (using CF Convention), and they are compatible with BRAT (Basic Radar Altimetry Toolbox) and other NetCDF tools (for instrunctions on how to open them with BRAT, see the dedicated section within this wiki). The Processors will make use of the G-POD ( Grid- Processing On Demand) distributed computing platform to deliver timely the output data products. The Sentinel-3 SAR Processor has two stages: L1b & L2. The manifest of these products are regurarly ingested in the G-POD storage facility so that they are made available in the G-POD data catalogue in order to be processed on line. The data products in input to the service are the Sentinel-3 SRAL L1A data products. The service is based on Sentinel-3 SARvatore Processor Prototype, heritage of the CryoSat-2 SARvatore Processor Prototype. The G-POD Service, SARvatore ( SAR Versatile Altimetric Toolkit for Ocean Research & Exploitation) for Sentinel-3, is a web platform that provides the capability to process on line and on demand Sentinel-3 SRAL L1A data products in SAR mode until Level-2 geophysical data products.
