This is a follow-up to the panel discussion held during the 2012 Forum. The session will provide additional opportunity for dialogue on the sources, distributors, and users of weather and climate data, with a focus on military applications. The panelists will be asked to discuss the following: The current status of the Defense Weather Follow-on System, the high priority geophysical observations for the defense community, the potential for a gap in these observations, and the potential for addressing these gaps via a variety of observing systems both military and civil. The discussion will include the topic of Unmanned Aircraft Systems (UAS) for weather and climate observations, and may address particular regional areas of interest such as the Arctic or Tropical Oceans.
