RAW: Raw Data

Figure 1. RAW Example Configuration

A RAW data file that contains the raw signal processor output parameters (Z, ZT, V, W, ZDR, and so on) in polar coordinates.

RAW products are made one-for-one from ingest files.

A RAW file contains all the information collected during a measurement task. It is compressed so it can be sent over the network to IRIS Analysis.

While RAW data cannot be displayed, it is useful for recording on tape/disk/DVD or transferring to another IRIS network computer for product generation.

When a RAW product file is either retrieved from tape or received from another IRIS computer, an ingest file is created so that products can be generated. The RAW product is used in the following ways:

  • Offline Analysis System: RAW products are stored on tape and later read back to an IRIS Analysis system (not necessarily the radar host) so products can be generated for analysis or testing.

  • Real-Time Network System: RAW products are sent to another IRIS computer and the product generation is done there rather than by the radar host. This off-loads some of the processing burden from the radar host onto other network computers that may be less busy. This is valuable if you want to generate products that are not normally produced by the radar host.
