OVERVIEW/ HOME

The AVDC

The Aura Validation Data Center (AVDC) is a centralized, long-term, archive for validation data hosted by the Atmospheric Chemistry and Dynamics Branch at the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. The AVDC mission is to support the Earth Observing System (EOS)-Aura validation and science activities, and the future “A-Train” Earth Science satellites validation activities.
Data archived at the AVDC originates from several special Aura validation campaigns, NASA aircraft and balloon deployments, established measurement networks for collection atmospheric data, the Network for Detection of Atmospheric Composition Change (NDACC), the Southern Hemisphere Additional Ozonesondes (SHADOZ), and the World Meteorological Organization (WMO)’s Global Atmosphere Watch (GAW), among others.
