In September 2012, the NASA Goddard Earth Science Data and Information Services Center (GES DISC) will host an online workshop focused on the use of the pioneering data visualization and analysis tool, Giovanni. The online workshop will be organized around four main themes: Earth system research utilizing Giovanni; Giovanni applications (air quality, disaster management, environmental monitoring, etc.); planned and desired augmentation of Giovanni; and educational use of Giovanni. The workshop will primarily consist of online author-led presentations coupled with real-time discussions about these presentations. Presentations and chat logs will be available online for review, for those not able to participate in live sessions. To indicate interest, please email Dr. James G. Acker, (james.g.acker (at) nasa.gov) or visit the workshop website for more information.
