The University of Wisconsin - Madison SSEC is pleased to announce the release of the CSPP Geo GRB Version 0.2 Prototype software package. This is the second release of software that will allow Direct Broadcast users to process GOES Rebroadcast (GRB) data received on their antennas from the GOES-R satellite, after it is launched in 2016. The software is publicly available and free to use.
The following new capabilities are included in this release:
Creates MAG and SEISS Level 1 products (in addition to the previously supported ABI Level 1 and GLM Level 2+ products)
Processes GRB data in the expected post-launch streaming data format, as received from a demodulator (CADU-framed CCSDS packets received over dual UDP sockets)
Output is written to mission-standard NetCDF-4 files. Optionally, quicklooks can be generated from the ABI radiance product.
The minimum system requirements for the CSPP Geo GRB software are:
12 core, 2.4 GHz CPU with 64-bit instruction support,
32GB RAM,
CentOS 6 64-bit Linux (or other compatible 64-bit Linux distribution),
100 GB disk space
Root access may be needed on the target machine to configure network buffer settings to the recommended sizes.
A test data package is provided, including scripts that simulate the GRB data stream by sending artificial data for each of the supported instruments over two sockets. In our internal testing, the software was able to keep up with the expected GRB data rate without packet loss when running on the recommended hardware.
Support for the remaining GOES-R instruments, SUVI and EXIS, will be added in a future release, as well as performance optimizations.
