WEB-GRAPE INTERNET BASED SERVICE AS AN INTERACTIVE TOOL THAT ALLOWS FOR POST-PROCESSING AND VISUALISATION OF ATMOSPHERIC TRANSPORT MODELLING SIMULATIONS: CURRENT STATUS AND PLANS FOR THE FUTURE

The Atmospheric Transport Modelling (ATM) operational system deployed and used at the CTBTO produces source receptor sensitivity (SRS) fields, which specify the location of the air masses prior to their arrival at any radionuclide station of the International Monitoring System (IMS) network. To enable visualisation of the ATM outputs and identification of possible source areas of radionuclide detections at IMS stations, the International Data Centre (IDC) has designed and developed the Web-connected graphics engine (Web-Grape) software and its online version, Web-Grape Internet Based Service (Web-Grape-IBS). Web-Grape IBS provides authorized users the capability for post-processing, visualizing and interactively analysing the products of the ATM pipeline through a web application, without the need to install commercial software on a local computer. Web-Grape IBS is integrated in the CTBTO’s Secure Web Portal and available to all authorized users via their Single-Sign-On credentials. This presentation will provide an overview of the available functionalities and will present functionalities that will be implemented in the near future. It also lays out a path forward for development of a desktop version, based on repackaging of Web-Grape IBS.
