The Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS→) – On-Demand System (COAMPS-OS→) is software developed at the United States Naval Research Laboratory (NRL) that the US Navy uses to run the COAMPS operational mesoscale numerical weather prediction system. In 2011, the NRL team released the first version of the COAMPS-OS Dashboard Viewer into operations at the US Navy's Fleet Numerical Meteorology and Oceanography Center (FNMOC) to meet the goal of integrating Geographic Information Systems (GIS) technologies into the system. The Dashboard is an advanced AJAX-based (Asynchronous JavaScript and Extensible Markup Language [XML]) web interface for creating, viewing, and exporting model visualizations, radar, satellite, model verification, and other standard GIS products in a properly geospatially-registered display. The Dashboard utilizes several open source tools such as MapServer, OpenLayers, and Google Web Toolkit (GWT) to provide an accessible, tailored, easy to use GIS interface in a web browser. With these new tools in COAMPS-OS, users have the ability to create their own map product layers, integrate other model forecast data (e.g., ocean models), overlay radar and other remote sensing observation layers, and add other geospatial intelligence information into a single application. A new version of the Dashboard client is currently in development, which will incorporate a completely new interface design using Sencha Inc.'s Ext GWT framework, new features including live spatial data querying and user sessions. It is scheduled to be included with the next major release of the COAMPS-OS software sometime in 2012.
