  5. + NASA/NOAA GTWS Wind Measurement Requirements (Partial List)Posted on Web on 16 Oct. 2001 – Errata Added Later

  6. + NASA/NOAA GTWS Wind Measurement Requirements (Partial List)Modified in 2005-2006 during NASA Lidar Technologies WG • Demo addition approved by NASA/NOAA GTWS SDT and by NASA HQ SMD ESD

  7. Yet More Changes • External Peer Review of Laser/Lidar Work at LaRC in Oct. 2007 • Criticized for not having technology path to all 3 sets of requirements • Criticized for showing requirements with “old” date of 2001 • Criticized for N/A’s listed for vertical resolution • Wayman Baker and others suggested sending Objective requirements to oblivion, leaving Demo and Threshold • Wayman Baker suggested 4 and 3 km for the vertical resolution requirement from 12 to 20 km for the Demo and Threshold missions, respectively • The NRC Earth Science Decadal Survey was published in Jan. 2007. It recommended two wind missions, “Demonstration” in 2016 and “Operational Demonstration” in 2022. • Wayman Baker and others suggested renaming the NASA/NOAA GTWS “Demo” to “Science Demonstration”, and renaming “Threshold” to “Operational” • May we have consensus on all these changes and call them the NASA/NOAA 2008 requirements?

NASA/NOAA 2008Wind Measurement Requirements Science Demonstration Mission Current Horizontal Wind Vertical Profile Observations ~23 km • Global averages • If 2 measurements in a box, pick best one • Emphasis on wind profiles vs. height Operational Mission Courtesy Dr. G. David Emmitt Note different color key
