Long-Term Archiving

Support for conscientious research data management: the DKRZ Long-Term Archive (DKRZ-LTA)

 

Keeping research data findable, accessible and (re)usable for the long-term is an integral part of sustainable research data management. This ensures clearly traceable provenance of scientific results in accordance with common rules of good scientific practice and is a prerequisite for research grant approval.

The start of offering long-term archiving and preservation of datasets relevant for climate science at DKRZ dates back to 1994. The DKRZ long-term archive (DKRZ-LTA) is certified according to the criteria of the ICSU World Data System and those of the "Core Trust Seal" (access the certification document) and is thus classified as a trustworthy data repository.

 

Depending on the needs for the preservation of individual datasets, DKRZ offers two flavours of its long-term archiving service: LTA WDCC ("World Data Center for Climate") or LTA DOKU ("DOKUmentation"). Both services build on the reliable and high-performance data storage capacities at DKRZ (DKRZ HPSS).

LTA WDCC: full-featured preservation of climate- and Earth System research data 

In the framework of the ICSU World Data System, DKRZ takes the role of the World Data Center for Climate (WDCC). Preservation of climate data and their detailed description suggests itself for datasets intended for re-use.

Data preservation in LTA WDCC - key aspects:

  • comprehensive consultation and support regarding the preparation of the data for long-term archiving
  • comprehensive technical quality assurance of the data
  • comprehensive description of the data ("metadata")
  • support of the "FAIR Data" principles for scientific data management and stewardshipFAIR logo larger
  • guaranteed long-term (>10 years) findability and (re)usability of preserved data 
  • allocation of DataCite DOI's to preserved datasets

LTA DOKU: simplified archival of publication- and project data

Preservation of research data in LTA DOKU is the simplified alternative to LTA WDCC. Data preservation in LTA DOKU is the ideal solution for datasets having to be archived and made accessible for reference purposes. These could be datasets underlying a scientific publication or which were created within externally-funded research projects. 

Data preservation in LTA DOKU - key aspects:

  • basic consultation regarding the preparation of the data 
  • guaranteed findability and accessibility of the preserved data for a period of 10 years
  • restricted to data associated with a registered DKRZ project

Data access

Data sets preserved at DKRZ - either in LTA WDCC or LTA DOKU - are findable and accessible via the central DKRZ CERA-Portal. Data access is free of charge and for the largest part unrestricted. However, you will need to register to get a user account.
