Data Transition
GOES-R Rebroadcast (GRB) Transition Information
The content distributed by GRB will be the full set of level 1b products, including data from all ABI channels and the other GOES-R instruments (GLM, MAG, SEISS, SUVI, EXIS).
GOES users must acquire new hardware, or upgrade their existing GVAR systems in order to receive GOES-R data.
Existing GVAR systems will need new receiver antenna hardware, as well as new signal demodulation hardware and computer hardware so that they are able to handle the large amount of GOES-R data.
CLASS will provide permanent archive for GOES-R data as part of its mission to be the single data repository for NOAA.
