ORNL DAAC? Oak Ridge National Laboratory’s (ORNL) Distributed Active Archive Center (DAAC) www.daac.ornl.gov • archives and distributes data for terrestrial biogeochemistry and ecosystem dynamics, including field campaign data (BOREAS, LBA, SAFARI 2000)
SAFARI 2000 OpenData 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)
SAFARI 2000 Data Archived Goddard DAAC • MODIS Airborne Simulator Data Langley DAAC • Air-MISR Data • MISR Data ORNL DAAC • Ames Airborne Sunphotometer Data • 25 regional SAFARI 2000 data sets • SAFARI 2000 CD #1
SAFARI 2000 Activities at the ORNL DAAC Provide data support to SAFARI 2000 investigators, including the Mercury system • Mercury is a web-based metadata search and data retrieval system • 36 SAFARI 2000 data sets registered in Mercury as of September 30 • 9 by SAFARI 2000 data team • 27 by SAFARI 2000 investigators

SAFARI 2000 Mercury: Searching for DataJuly 1, 2001 – September 30, 2002 Number
SAFARI 2000: Most Referred Data SetsJuly 1, 2001-September 30, 2002(180 data referrals, 68 users)
Subset from 1200 x 1200 km to 7 x 7 km to relate to field work • Reformat from HDF image into ASCII file of pixel values and QA flags, expanding as data are collected Posting MODIS ASCII Subsets at the ORNL DAAC • MODIS Products: • Veg Index • fPAR / LAI • Future (2003) • PSN / NPP • NBAR and • Surface • Reflectance • Surface • Temperature • LC/LCC Mongu Tower Site, 2001
MODIS ASCII Subsets in Southern Africa Current Sites (Collection 3 Processing) • Skukuza Tower (South Africa) • Mongu Tower (Zambia) Additional Sites (Collection 4 Processing; early 2003) • Maun Main Tower (Botswana) • Maun Floodplain Tower (Botswana) • Tshane (Botswana) • Okwa River Crossing (Botswana) • Pandamatenga (Botswana) Collection 4 backward processing will include historical MODIS data collected from as far back as March 2000
Next steps: Based on the SAFARI 2000 Data Policy • SAFARI 2000 Investigators need to register their data sets in Mercury and make the metadata searchable • Regional investigators who initiated their registration at Siavonga • Contributors to the four special issues • 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 (understandable 20 years from now)
