Mseed data format

Mseed data format-SWC retrieves data in miniSEED format (no instrument response metadata) Instrument response metadata can be retrieved through web services as dataless seed (readable with rdseed), resp file format, or station XML Full network IR metadata is available in our network directoriesThe SeedLink protocol is a robust data transmission intended for use on the Internet or private circuits that support TCP /IP The protocol is robust in that clients may disconnect and reconnect without losing data, in other words transmissions may be resumed as long as the data still exist in the servers buffer

Seismic data are widely stored and exchanged in SEED format In current usage, these data are commonly divided into a file of slowly changing metadata, called aData are selected using SEED time series identifiers (network, station, location & channel) in addition to time ranges Data are returned in miniSEED, SAC zip, and GeoCSV format This service is an implementation of the FDSN web service specification version 1 NOTE polling for realtime continuous data is not allowedWeb Services retrieve data in miniSEED format (no instrument response metadata) Instrument response metadata can be retrieved through web services as dataless seed (readable with rdseed), resp file format, or station XML Full network IR metadata is available in our network directories More About Accessing NCEDC Web Services

The start and end times are specified in an ISO defined format, with a capital 'T' separating the date from the time Commas are also permissable to separate the date and time components The received miniSEED will be saved to the GSNmseed file and simple ASCII metadata will be saved to the GSNmetadata fileMost of the waveform data can be categorized as passive source seismic data collected by broadband, strongmotion and analog instruments Digital Seismograms Most of the seismic waveform archive exists as digital waveforms, single value timeseries stored in miniSEED format The SCEDC has event based time windows, or gathers, sometimes calledField Archive projects perform recurring data retrievals, storing the time of the current retrieval on the Nanometrics instrument Data for time series channel groups can be downloaded in MiniSEED, SAC (binary format), Seisan, or SEGY format, depending on the project type View the Brochure

Submitting SEED data ¶ Data can be submitted to the DMC by tape or over the Internet Network operators are encouraged to submit data in SEED format in nearreal time This "concurrent" method of data submission is beneficial to the network operator because much of the data handling and archiving issues are removed from their routine and they are able to request their data fromCss30 Databases in Center for Seismic Studies 30 schema format This is the relational database format used by Antelope, and used heavily in nuclear test monitoring and regional earthquake monitoring communities The most important database tables are origin (which contains event metadata) and wfdisc (which describes the waveform data available)In 1987, the International Federation of Digital Seismograph Networks (FDSN), adopted the Standard for the Exchange of Earthquake Data (SEED) format to be used for data archiving and exchange of seismological time series data Since that time, the format has evolved to accommodate new capabilities and features For example, a notable change in 1992 allowed the format
