National Academy Decadal Study: Earth Science and Applications from Space  Charge: –Review the status of the field –Develop a consensus of the top-level scientific questions that should provide the focus for Earth and environmental observations in the period –Take into account the principal users of these observations, including a range of applications with direct links to societal objectives, and identify opportunities and challenges to the exploitation of the data generated by Earth observations from space. –Recommend a prioritized list of measurements and identify potential new space-based capabilities and supporting activities within NASA, NOAA and USGS to support national needs for research and monitoring of the dynamic Earth system during the decade –Identify important directions that should influence planning for the decade beyond  

NAS Decadal Study Panels   Seven Panels –Earth Science Applications and Societal Needs –Land-Use Change, Ecosystem Dynamics and Biodiversity –Weather (including space weather and chemical weather) –Climate Variability and Change –Water Resources and the Global Hydrologic Cycle –Human Health and Security –Solid-Earth Dynamics, Natural Hazards, and Resources  Weather Panel Focus (co-chairs: Susan Avery and Tom von der Haar) –Observations that improve prediction of weather, including weather hazards such as flooding, severe local storms, tropical cyclones and fires; –Observations that improve predictions and understanding of space weather; –Observations that improve prediction and understanding of air quality (i.e., “chemical weather”); –The role of assimilation of satellite products in addressing the problems of prediction; –New and improved forecast products for a variety of users, including aviation, surface transportation, homeland security, agriculture, energy, water, etc.

Weather Chemical Weather Space Weather Weather Panel Presentation at 2005 AGU Annual Meeting

Key Issues Presented by Weather Panel at AGU  Weather, Chemical Weather, Space Weather (Vision and Roadmap)  Existing missions; Capacity/future of NPOESS  Societal Application and Impact –Mitigation of natural and human-induced hazards –Economic decision-making –Decision-support tools  Reviews of RFI responses/presentations –Breakthrough science –Societal impact –Forecasting improvements and applications –Risk (technical, cost, readiness) –Other attributes (international strategic directions; potential cross-panel interest; supporting activities)  Overlap with other panels (climate, water, health, applications)

Weather Conceptual Missions (from AGU)  Weather –Tropospheric winds –High time resolution all-weather –Radio-occultation follow-on –Clouds and aerosols  Chemical Weather –GEO air pollution –Global tropospheric aerosols –Global ozone –UAV tropospheric measurements  Space Weather –Solar monitor –Ionospheric mapper –Space weather buoys –Radio-occultation follow-on Decadal study report scheduled for release late 2006
