What we are lackingCentral data facility (archive) Achieved
Data comparison standards Proposed (some occurring)
Detailed soil temperature dataRegular soil moisture data Adding spring ‘02
Short term archive (2 days - 6 weeks) In progress
Improved spatial and temporal resolution In progress (SCAN/CRN Schoolnet)
