Retrieve waveforms via FDSN webservice

fdsnws: <network> <station> <location> <channel> <start> <seclength>

or
fdsnws: <bulkfile>

Description

parameters

  • <network> parameter type: string
    Network code or comma separated list of network codes to request stations from. Examples "GR" or "GR,TH".
  • <station> parameter type: string
    Station or comma separated list of stations data from. Accepts wildcards. Examples "GRA1", "GRA1,GRA2", "GR*" or "*".
  • <location> parameter type: string
    Location code or comma separated list of location codes. Accepts wildcards. Examples ",00" or "*".
  • <channel> parameter type: string
    Channel code. Accepts wildcards. Examples "BHZ", "BH*" or "*".
  • <starttime> parameter type: string
    Start time in SH notation. Example "12-Jul-2015_06:30:22".
  • <seclength> parameter type: float
    Length of requested data window in s.
  • <circledef> parameter type: list of float
    Comma separated triple of floating point numbers, specifying latitude, longitude of a location on earth and radius in deg around this point. Data from all stations known to the FDSN server and located in this circle around point (latitude,longitude) are returned in this request. Example "49.,11.,1.".
  • <bulkfile> parameter type: string
    File containing the data request to the FDSN server. Format see qualifier "/bulkline". Currently FDSN servers deliver data which are not properly aligned to the time windows specified, but contain complete SEED records.

qualifiers

  • /addr
    Specify FDSN server or alias name. Default server is read from configuration file, section [fdsnws], variable "default_data_source". Known server names are "BGR", "GFZ", "INGV", "IRIS" and others, see ObsPy? documentation.
  • /bulkline
    Do not process the given request but return a line for a bulk request. Combined with the "echo" command a bulk request file can be assembled. Does not work with <circledef> parameter.

example

fdsnws
fdsnws gr gr* * bhz 17-aug-15_8:30 300
Reads five minutes of GRF array data from the default FDSN server. See "help;; command for more examples.
