EISCAT_3D Data Management Plan
The EISCAT_3D system represents a significant upgrade to EISCAT’s incoherent scatter radar (ISR) capabilities. The system is designed with a great deal more flexibility than the present EISCAT ISRs can provide, largely through the use of signal digitization very early in the processing chain and the use of a very large number of smaller antennas. Internally, this represents an extremely large amount of data bandwidth, on the order of a few terabytes per second. The data streams from the individual antennas are, however, of little use unless they are combined and this combination can be accomplished at various stages in the system, thus greatly affecting the load on the data processing and communication subsystems. Data management and data processing management are, as a result, important considerations in the system architecture and operation.
