AB: Validation of Aura data: needs and implementation L. Froidevaux, A. R. Douglass, M. R. Schoeberl, E. Hilsenrath, D. Kinnison, M. Kroon, and S. P. Sander We describe the needs for validation of the Aura scientific data products expected in 2004 and for several years thereafter, as well as the implementation plan to fullfill these needs. Many profiles of stratospheric and tropospheric composition are expected from the combination of four instruments aboard Aura, along with column abundances, aerosol and cloud information. The Aura validation working group and the Aura Project have been developing programs and collaborations that are expected to lead to a significant number of validation activities after the Aura launch (in early 2004). Spatial and temporal variability in the lower stratosphere and troposphere present challenges to validation of Aura measurements even where cloud contamination effects can be minimized. Data from ground-based networks, balloons, and other satellites will contribute in a major way to Aura data validation. In addition, plans are in place to obtain correlative data for special conditions, such as profiles of O3 and NO2 in polluted areas. Several aircraft campaigns planned for the 2004-2007 time period will provide additional tropospheric and lower stratospheric validation opportunities for Aura; some atmospheric science goals will be addressed by the eventual combination of these data sets. A team of "Aura liaisons" will assist in the dissemination of information about various correlative measurements to be expected in the above timeframe, along with any needed protocols and agreements on data exchange and file formats. A data center is being established at the Goddard Space Flight Center to collect and distribute the various data files to be used in the validation of the Aura data.
