Scientific requirements
SIOS core data are essential in answering the Earth System Science questions defined in the SIOS infrastructure optimisation report, and further update in SESS reports.
Data availability
SIOS core data should be available through the SIOS Data Management System (SDMS). SIOS core data candidates should be available as soon as possible and at latest one year after data collection.
Collecting commitment
For SIOS core data there should be a more than 5-year commitment from the providing institute to maintain the measurement and to make the data available through SDMS.
