| BUD | The Buffer of Uniform Data is the online data cache from which we distribute our near-real time miniSEED data holdings prior to formal archiving. |
| Dataless SEED | header information in SEED format with the time series omitted. |
| DHI | The Data Handling Interface [DHI] is a CORBA data access framework allowing users to access seismic data and metadata from IRIS DMC and other participating institutions directly from a DHI-supporting client program. |
| DMC | The IRIS Data Management Center archives and distributes data to support the seismological research community. The data center is located near the University of Washington in Seattle. Read More |
| DMS | The IRIS Data Management System [DMS] consists of several components or "nodes" that work together to ensure the smooth flow of GSN and PASSCAL data from the stations to the seismological research community. Read more |
| E&O | IRIS Education and Outreach Program |
| EarthScope | EarthScope is a program of the National Science Foundation (NSF) that deploys thousands of seismic, GPS, and other geophysical instruments to study the structure and evolution of the North American continent and the processes the cause earthquakes and volcanic eruptions. It involves collaboration between scientists, educators, policy makers, and the public to learn about and utilize exciting scientific discoveries as they are being made. |
| FARM | Fast Archive Recovery Method - FARM is IRIS DMC's readily-accessible seismic event data repository (delayed, QC'd, full data set). |
| GSN | The Global Seismographic Network (GSN) is a 150+ station, globally distributed, state-of-the-art digital seismic network providing free, realtime, open access data through the IRIS DMS. Read more |
| IEB | IRIS Earthquake Browser is a web based earthquake query tool. |
| IRIS | IRIS is a consortium of over 100 US universities dedicated to the operation of science facilities for the acquisition, management, and distribution of seismological data. IRIS programs contribute to scholarly research, education, earthquake hazard mitigation, and verification of the Comprehensive Nuclear-Test-Ban Treaty.

| MDA | MetaData Aggregator (MDA) - a web interface to communicate with the IRIS DMCs Oracle database to provide a combination of key metadata parameters in a fast and useful way. |
| 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 form. Read more |
| PASSCAL | Program for Array Seismic Studies of the Continental Lithosphere. The PASSCAL facility provides the seismological community with state-of-the-art, low-power, portable seismic instrumentation in support of investigator-driven seismological experiments worldwide. |
| PDCC | Portable Data Collection Centers (PDCC) software provides network operators a portable software facility for managing seismic network data and metadata. |
| Quack | Quality Analysis Control Kit (QUACK) is a software package at the IRIS DMC for analyzing real-time seismic data flowing into the BUD (Buffer of Uniform Data). |
| rdseed | Read an FDSN SEED format volume. Read more |
| SEED | Standared for the Exchange of Earthquake Data [SEED] is a digital earthquake data format consisting of "blockettes" of header and binary data. |

| SPUD | The Searchable Product Depository (SPUD) is the IRIS DMC's data product management system. |
| SPYDER | SPYDER® is IRIS DMC's near-real-time data retrieval system. SPYDER® data is not QCed but is available almost immediately after an event. |
| USArray | USArray, which is part of the EarthScope experiment, is a 15-year program to place a dense network of permanent and portable seismographs across the continental United States. General USArray information: http://www.usarray.org/ USArray activities at the IRIS DMC: http://www.iris.edu/earthscope/usarray/ |
| VASE | The Visualization and Seismogram Extraction (VASE) tool is a Java-based client application designed for viewing and extracting seismic waveforms from the DHI waveform repository via BUD. |
| WILBER | Waveform browsing and request tool. WILBER II allows you to select from a catalog of events for which the DMC has SPYDER® and/or FARM data products (waveforms). |
