Pricing Policy for Digital Research Data Archives

Not every digital research data archive is fully funded. Charging fees for data services may help archives to survive. Archives which follow this funding stream have to decide who has to pay, data producers or users, and how much. For the calculation of data service prices a multi-linear price function is suggested. Variables are the number of datasets and the data volume. Different user requirements and data complexity are mirrored as service levels in the price function. Its utilization is shown in a case study at the World Data Centre for Climate (WDCC)

IPCC-DDC at WDC Climate / DKRZ

The talk given at the IPCC AR6 Data Workshop (19/20 September 2017) at DKRZ in Hambrug, Germany, between IPCC AR6 Working Group I and II TSUs and IPCC DDC Managers from BADC and WDCC/DKRZ gives an overview over the current data services within the IPCC Data Distribution Centre (DDC) hosted at DKRZ and the future plans to improve the support for the IPCC Working Groups and their authors during the 6th assessment cycle

The Earth System Grid Federation: Delivering globally accessible petascale data for CMIP5

The fifth Coupled Model Intercomparison Project (CMIP5) will involve the global production and analysis of petabytes of data. The Program for Climate Model Diagnosis and Intercomparison (PCMDI), with responsibility for archival for CMIP5, has established the global “Earth System Grid Federation” (ESGF) of data producers and data archives to support CMIP5. ESGF will provide a set of globally synchronised views of globally distributed data – including some large cache replicants which will be persisted for (at least) decades. Here we describe the archive requirements and key aspects of the resulting architecture. ESGF will stress international networks, as well as the data archives themselves – but significantly less than would have been the case of a centralised archive. Developing and deploying the ESGF has exploited good will and best efforts, but future developments are likely to require more formalised architecture and management
