Lautenschlager + Thiemann (M&D/MPI-M) / 29.03.06 / 15 Start: Approved in January 2003 Maintenance: Model and Data (M&D/MPIMET) and German Climate Computing Centre (DKRZ) Mission: Data for climate research are collected, stored and disseminated ICSU Policy: long-term archiving and unrestricted data access for scientists Restriction: Only climate data products in CERA DB, no raw data storage. Content: Emphasis is on climate modelling and related data products. Co-operation: with thematically corresponding data centres like WDC- MARE (Bremen) and WDC-RSAT (Oberpfaffenhofen) URL: http://www.wdc-climate.de/http://www.wdc-climate.de/ WDCC The WDCC is IMDI's central component for data archiving and data dissemination
