The Next Generation Air Transportation System (NextGen) is a multi-agency effort that relies on a network-enabled infrastructure for sharing of information of all types, including weather information. The NextGen Network Enabled Weather (NNEW) program is specifically focused on the sharing of weather information and the particular challenges associated with the distribution of data sets that can be grow to be quite large when compared with other types of air traffic management related data. When dealing with large data sets, for example, it becomes increasingly important to provide robust data discovery and subsetting mechanisms, allowing users to request data for only a specific geographical region and/or time period of interest.

NextGen information management as a whole will leverage a set of core capabilities and common infrastructure, allowing the system to be scalable, secure, and maintainable. The FAA's System Wide Information Management (SWIM) program is putting in place many of the key elements of the network-enabled infrastructure for the National Airspace System (NAS). In order to conduct real-world testing of the infrastructure during the SWIM development phase, the program has established a testbed at the WJHTC Development Operations Center (DOC) in Atlantic City. This paper will describe the activities involved in integrating nascent and existing NextGen agency net-enabled weather capabilities within the DOC. One of the key integrated components will be the US Air Force's Joint Environmental Toolkit (JET), allowing FAA access to well-established Air Force data feeds as well as information from the NWS's National Digital Forecast Database (NDFD). Experimental forms of the FAA's Corridor Integrated Weather System (CIWS) and Aviation Digital Data Service (ADDS) will also provide weather data and services potentially using Open Geographic Consortium (OGC) standards. Lessons learned from this multi-agency network enabled work will be included and will be used as risk reduction within the SWIM Weather Community of Interest, the NNEW program, and in developing the NextGen 4-dimension weather information cube.
