DKRZ long term archive
The German Climate Computing Center (DKRZ: Deutsches Klimarechenzentrum GmbH) 
provides a Long Term Archiving Service for large research data sets which are relevant for climate or Earth system research. This service includes archiving and retrieval capability of data for time periods of 10 years or longer. The long-term archive (LTA) of DKRZ is certified according to the criteria of the Core Trust Seal (CTS) and is, as World Data Centre for Climate (WDCC), accredited as regular member of the World Data System.

Data access The graphical web interface of the DKRZ long-term data archive offers a wide variety of search options based on the stored metadata. These allow a quick discovery of the data desired, sorted by project, topics, temporal and spatial coverage, or other facets. Get started by clicking here.
Data from the long-term archive are downloadable either by using the graphical user-interface or by the command line tool jblob. Access and download is free of charge. Licenses which regulate the use are provided for all data objects.
Data archivingLTA WDCC is the long-term archiving service in the WDCC. This service is available for DKRZ HPC project data as well as data from external sources. Conditions for this need are to be negotiated. The full set of metadata facilitates the interdisciplinary reuse.
LTA DOKU is an additional service for DKRZ HPC users and offers long-term archiving for data of DKRZ HPC projects as reference data only. A basic set of metadata, supplied by the data producer, describes the data and make it easily findable in the long-term archive.
Data publication The data publication process is similar to the publication of an article in a scientific journal. Data, published with a DOI at WDCC has to meet certain quality requirements. The permanent access to data is granted by the assigned unique persistent identifier DOI - data and metadata remain unchanged.
DataCite DOI data is formally citable in scientific paper publications along with literature citations and counts towards the data creator's list of scientific publications.
