DKRZ long term archive

The German Climate Computing Center (DKRZ: Deutsches Klimarechenzentrum GmbH) dsaprovides 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.

DOIs assigned to MeRamo
DOIs doi:10.26050/WDCC/MeRamo_exp1, doi:10.26050/WDCC/MeRamo_exp2 and doi:10.26050/WDCC/MeRamo_exp3 are assigned to experiments in project MeRamo (HBM-ERGOM western Baltic Sea simulations with tagging of atmospheric nitrogen deposition within the MeRamo project).
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. Browsing can be done by project, topic, temporal and spatial coverage and some other facets. You can also do further searches by using the free text function. Get started by clicking here.

Results from searching and browsing are presented as catalogue records providing essential information and links to further information about each data entity. Data from the long-term archive can be downloaded 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 archiving
The DKRZ provides two different tiers of long-term archiving:
- LTA DOKU offers long-term archiving for data of DKRZ HPC projects as reference data only. A basic set of metadata has to be supplied in order to describe the data and make it easily findable in the long-term archive.

- LTA 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 needs to be provided in order to facilitate interdisciplinary reuse.
Data publication
The DKRZ offers a DataCite data publication service for long-term archived data. Published Data is granted permanent access 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 can be entered in the data creator's list of scientific publications. For the DOI publication at WDCC data has to meet certain quality requirements. The data publication process is similar to the publication of an article in a scientific journal.

Software updates are performed from 8:00 to 10:00 CEST on Mondays, therefore access to the user interface of the DKRZ long-term archive, CERA, might be unavailable during this period of time.
