Request Network Code

Permanent Networks

Permanent networks should:

  • expect to operate continuously for the foreseeable future,
  • have a relatively stable set of stations and instruments, and
  • distribute data in the FDSN SEED format.

Temporary Networks

Short-term deployments, active source experiments, or networks that produce non-SEED (eg. SEGY) data should request a temporary network code.
