Access and use of NASA and other federal Earth science data

This session explores experiences of Earth science data users, including researchers, public, and developers, and discusses challenges new users face in accessing, using, and interpreting data. Examples of federal Earth science data platforms and initiatives are shared, alongside strategies to improve data discoverability, accessibility, and usability for users. The panelists provide insight into patterns of new data users and suggest ways data providers can better support users. Contact information for key presenters is also provided for further inquiries.

  1. Access and use of NASA and other federal Earth science data Ethan McMahon ESIP Summer Meeting July 8, 2014

  2. Today’s session From the data user perspective • Introduction • Panelists describe experiences of data users • Discussion

  3. The Problem • There are many audiences of Earth science data (aka data users) • Researchers • Interested public • Software developers • These users wantdata for different purposes • They want more and more data • What are their experiences and how can data providers help?

  4. New data users • Interested public (communities, non-profits) • Perform their own analyses • Gather and interpret data (citizen science) • Software developers • Create green apps • Have the desire but not the context

  5. Experience with developers • Developers try to find the data but many cannot • Some ask about the data and get answers from experts • Others try to use the data but are not successful • No experts • Poor documentation • Unusable formats • How can we help them do good?

  6. Examples of federal Earth science data • Global Change Master Directory • Giovanni • Earth Explorer • National Climatic Data Center • Environmental Dataset Gateway • Data.gov

  7. Big Earth Data Initiative • Seek agreement on common approaches for • Discoverabilityvia catalog services and search engines • Accessibility via online data services • Usability via standard formats, metadata, vocabularies

  8. Today’s panelists • Tamara Ledley of TERC • Janet Fredericks of Woods Hole Oceanographic Institution • Margaret Mooney of the UW-Madison Cooperative Institute for Meteorological Satellite Studies • Rob Carver of The Weather Channel

  9. Discussion • What are your experiences in accessing and using these data? • What are the patterns of these new data users? • How can we help users use the data appropriately? • What else can data providers do to help?

  10. Contacts • Tamara Ledley • tamara_ledley@terc.edu • Janet Fredericks • jfredericks@whoi.edu • Margaret Mooney • margaret.mooney@ssec.wisc.edu • Rob Carver • rob.carver@weather.com • Ethan McMahon • ethan.m.mcmahon@nasa.gov
