SAFARI 2000 Open Data Policy Provide timely access to data while protecting the

intellectual property rights of students and investigators, and giving credit to data originators

SAFARI 2000 participants are expected to register their metadata in Mercury

SAFARI 2000 data will be made available project participants as soon as possible and to the public by June 30, 2003

Project data will be archived at the regional data center and at the ORNL DAAC or other DAAC (e.g., Langley or Goddard DAACs)

Contributors to the SAFARI 2000 Synthesis Workshop

By June 30, 2003, all S2K investigators need to make their data available to the public

S2K Leadership needs to decide which data sets should be archived at NASA DAACs and at the regional data center Data sets selected have to be thoroughly documented
