C3 Architecture

Portal, resources at different sites and the distributed infrastructure is connected via interfaces. The following figure illustrates the interaction.


The Portal is the place for data query, selection and job submission. A workflow scheduler allocates the available resources. The C3Grid provides combined storage and processing facilities in the German climate community. A scientific workflow is doing the data access, pre processing, data volume reduction (e.g. temporary or geographical cut, variable selection) and the generation of the requested output, e.g. in GRIB or NetCDF.
