1. Wayman initiating new start proposal for FY09 budget cycle.
2. Recent roadmap inputs from LRRP, ESTO WG, industry, June LWG meeting.
3. Next step is to update DWL roadmap. Key milestones would be:

  · Hybrid space demonstration via either STP, NPOESS P³I, or possibly ADM follow-on mission (possible scenario with the Japanese is unknown)
  · Operational NPOESS mission.
  · Ken Miller draft revised roadmap and circulate it to the Interagency WG.

  · Models that predict photometric return from a space-borne instrument given the laser power, telescope size, orbit, and atmospheric properties.
   Instrument model, validated by lab measurements, that predicts the measured signal level for a given photometric return.
  · Shown precision within 2x the statistical signal limit when detector read and fixed-pattern noise sources are negligible, and continue to improve this factor.
  · BalloonWinds will make downward measurements to validate 355-nm photometric return models (1) and characterize precision of the velocity measurement with the new detectors.

6. How to approach NASA HQ on the importance of tropospheric winds needs to be discussed, including how the measurements could be valuable in gaining a better understanding of the atmosphere of Mars.

Extensive materials prepared for NRC decadal survey, ESTO Lidar Working Group (LWG), management white paper.

ESTO LWG identified trop winds demo as the single highest priority mission in the oeuvre. The overriding criterion was "societal benefit," based on mitigation of severe weather impacts. LWG reported to George Komar (Acting Chief Technologist for the NASA Science Mission Directorate) on June 15, 2006. The priority position of a winds demo mission was discussed. It was pointed out that while the case might be contested that other measurements were equally important (or even more so), that nevertheless the observed impact of a winds mission would be felt much sooner than other competing measurements. Hence its ranking in the working group's report. Ramesh emphasized the need.
