1. 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 2005-2015. –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 2005- 2015. –Identify important directions that should influence planning for the decade beyond 2015.   http://qp.nas.edu/decadalsurvey

2. 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.
