Technology Advisory Committee (TAC) Charge

1. Technology Advisory Committee (TAC)Charge • Familiarize itself with strategic plans and emerging technologies. • Evaluate issues and opportunities associated with sensors, data services, and operations research. • “In consideration of ATD core competencies and the unique role of multi-user observing systems, advance thematic proposals pertaining to ATD’s key contributions over the coming decade.” • “Stratify thematic proposals into technological or applications categories, such as optical remote sensing, precision in situ sampling, airborne remote sensing, etc.”

2. What Constitutes a Technological or Applications Thematic Proposal? • Examples given: optical remote sensing, in situ sampling, airborne remote sensing. • Develop vs. apply technology. • Theme qualification: Envision ATD Institute of XYZ Technology (incorporates development and application). • Does ATD Institute (future group organization?) make sense “In consideration of ATD core competencies and the unique role …”? • How much consideration should be given to present ATD core competencies vs. ATD of the future?

7. Technological Themes • Coupled Observations/Assimilation • Package data for ready assimilation into models • Integrate assimilation and model output into real time “products” for field control centers • UAV and Pod Mounted Instruments • Miniaturized instruments, MEMS • Advanced power systems • Composite materials utilization • Data sampling for speed, range, and duration

8. Technological Themes • Inlet Design and Airflow Engineering • Airflow modeling and CFD analysis for airframes, instruments, and pods • Air inlet sampling systems for gases and aerosols up to max HIAPER airspeed (Mach 0.8)

9. Engineer Ballot • The TAC understood from Rit that about 5 themes are to be offered (at some stage in the process). • Engineers and other interested persons were asked: “Please rank the list from 1 to 9, with 1 being in your opinion, the technology area which has the potential to bring the greatest impact to atmospheric or related sciences. If some are tied in priority, favor the ones for which you believe ATD has or could develop the best expertise.” • Please provide comments.

11. Selected comments from ballots • Difficult to prioritize: All relevant, built in bias, lots of overlap (reorganize themes?), need science oversight/guidance, we should be involved in all the themes. • Cost/Benefit analysis? • Some themes are instrument specific, others are not. • Emerging technological opportunities as a theme? • Ship borne not mentioned. • We should concentrate on system engineering and developing integrated sensor systems. • We should concentrate on developing fewer systems to turn-key completion. • How about a theme on sensor technology (technology as a technological theme)? • Combine assimilation and cyber-infrastructure. • How about testing/calibration/validation (should be part of any theme) as a theme itself?

12. ATD Engineering “Process” • More interaction with the profession: Conferences, seminars, sabbaticals, visitors. • Designated system or project lead engineers. • Collaboration w/ outside groups. • Share engineers among projects. • More formal practices. • More engineering research, basic and applied.
