This statement of work is the result of a proposal submitted by sensis corporation for award in response to NASA headquarters aeronautics research mission directorate (ARMD) NASA research announcement (NRA) entitled research opportunities in aeronautics 2007, amendment 4, topic 5. This research activity is sponsored by the NASA airspace systems program, nextgen airspace project, and performance based services research focus area. Scope of work: the scope of work for this research effort is contained in four principal objectives: 1) provide the capability to synthesize and use simulated convective weather scenarios; 2) provide relevant categorized recorded weather data scenarios; 3) identify specific weather scenarios that will have a high impact on particular air traffic operations and scenarios; and 4) provide support for incorporating these scenarios into the atos environment, which is hosted in the air traffic operations lab, or atol, at NASA langley research center. The last objective includes developing the capability to convert raw convective weather data into polygons for use within atos. The tasks and deliverables that address each of these four objectives are described in sections 4.1 through 4.4 and 5.1 through 5.4, respectively. Description of tasks/technical requirements: the following tasks shall be performed by the contractor: 4.1 convective weather scenario generator. The contractor shall develop the capability to generate generic, parametrically-specified convective weather conditions, forecast products, and compatible wind and temperature fields for use in simulations of generic, or randomly generated, traffic scenarios. Key parametric controls (e.g., coverage, growth, dispersion, and movement) shall be identified and implemented. The contractor shall develop software tools that will generate these generic, parametrically-specified convective weather scenarios and associated forecasts, and usage documentation as described in section 5.1.2. The contractor shall demonstrate use of these software tools at the meetings identified in section 5.1. 4.2 weather scenarios database. The contractor shall use the atol weather scenarios database requirements document provided by NASA, to assemble and categorize a database of suitable weather/traffic scenarios based on six months of previously-recorded and/or newly acquired weather data. Once the contractor receives the requirements document, they shall consult with the NASA technical monitor regarding the specific six-month weather acquisition period. The quantity of data shall be sufficient to produce a variety of representative weather patterns and conditions that affect ATM operations (e.g., squall lines, air-mass convection, icing, and turbulence). 4.3 high-impact weather/traffic scenarios. Based on the contractor S assessment of the NASA experiment activities, knowledge of the weather scenarios database, and understanding of current-day ATM/weather interactions, the contractor shall analyze the recorded weather and traffic data and identify at least 10 high-impact scenarios in which trajectory-based operational concepts have the potential to significantly improve and/or degrade performance relative to current operations in the presence of weather. The contractor shall document these scenarios along with the rationale for selecting them, and shall present these findings to NASA for consideration in future ATM studies. 4.4 atos integration of weather scenarios. The contractor shall develop software that will convert raw convective weather data into polygons for use within atos, and shall provide usage documentation and demonstrations of this software S capability to NASA. The contractor shall be available to answer questions from the atol/atos software support contractor regarding software integration and testing to ensure that this weather data format conversion software works properly with the appropriate atol simulator applications.
