IRIS Knowledge Base

Data Access Navigator Tool      

To assist new and experienced users alike in navigating IRIS DMC's waveform request tools, a navigation page has been provided on the web that helps to highlight the most important methods of data access.  Please consult the Data Access Tool here.  Below are specifics on some of the most commonly used waveform reqeuest tools.

Request Waveform Data Using BREQ_FAST

Batch access to the IRIS DMC archive can be obtained by electronically mailing a specially formatted file to the IRIS DMC in Seattle.  These are BREQ_FAST files and provide a base level access to the DMC needed by any user. Learn how to submit a BREQ_FAST Request.

Buffer of Uniform Data

BUD is the IRIS DMC's acronym for its real time data buffer.  There are web tools to access data in this buffer as well as a SeedLink server for streaming data in near-real time.  Learn more about BUD.

WebRequest - A web form for submitting BREQ_FAST requests

WebRequest is a data request form that allows users to submit BREQ_FAST-formatted data requests to the DMC. Go to WebRequest.

NetDC - Networked Data Center Protocol 

NetDC is a data request system that allows a user to request seismological information from multiple data centers through a single email mechanism. Information is delivered to the user through email and/or FTP in a uniform binary or text format. Learn more about NetDC.

SOD - Standing Order for Data

SOD is a client program that automates the process of event detection, data selection, downloading, and routine processing tasks in seismology.  It allows you to define your desired data based on earthquakes, recording stations, and the resulting combination of information. SOD then retrieves the data that matches the criteria when such quakes occur. Learn more about SOD.             

JWEED

JWEED is a Java client that allows a user to find earthquakes, locate stations, and gain access to data using phase arrivals as time windowing operators.  A WMS scalable map facilitates visualization and selection of earthquakes and stations.  Data can be plotted on the screen or downloaded to disk in a number of different formats.  Learn more about JWEED.
