miniSEED to SAC
2011-09-07 18:29:45
Hi,

I received some raw data in miniSEED format.
How do I go from miniSEED to SEED? I have the station's location, elevation
and poles&zeros.
I tried to search online and in the SEED documentation, but couldn't find an
explanation on how to go from miniSEED to SEED or how to create a dataless
SEED for that purpose.

Thanks,

Shahar

    Hello, Shahar-

    The easiest way to get fulllSEED from miniSED is to first get a dataless SEED volume
    (there are numerous network dataless volumes available online at
    http://www.iris.edu/pub/RESPONSES/DATALESS_SEEDS/
    and then use the program "rdseed"
    http://www.iris.edu/forms/rdseed_request.htm

    The manual for rdseed is online at http://www.iris.edu/manuals/rdseed.htm
    and look for the "ENVIRONMENT VARIABLES" link at the top "Jump To:" section,
    where you set the ALT_RESPONSE_FILE variable that enables you to read in
    miniSEED, and output fullSEED.
    Let me know if you need more help than this.
    Regards,
    Rick

      Hello Shahar,

      Another option would be to use the mseed2sac converter, the source code is available here:

      http://www.iris.edu/pub/programs/converters/

      mseed2sac will take a simple ASCII text file that contains the lat, lon, elev and other simple metadata for the time series and insert those values into the SAC headers during conversion. This format of the text file is documented in the man page included with the source code. There is also an option to insert values into the SAC event headers during conversion if you want that information included.

      regards,
      Chad

        Dear All -

        MacSAC reads miniSEED directly. There is no reason why IRIS SAC couldn't either, and eliminate the conversion steps outlined.
