Stations and Data

Seismic Data Access and Availability (new policy beginning February 2011)

Seismic data from the AfricaArray observatories are being archived and distributed by the IRIS Data Management Center under the network code AF. The data can be viewed at: http://www.iris.edu/mda/AF and can be obtained using standard data request tools at IRIS.

Beginning February 2011, all data for the following stations are open immediately:

SHAI, KUKU, IFE, YNDE, AAUS, TEBE, NBI, RUSH, GETA, DODT, MBEY, MTVE, MZM, ZOMB, LBB, TETE, TEZI, RUDU, WIN, POGA, SOE, SVMA, SKRH

For the remaining stations, the data are openly available after three years. The first open release was in October 2009 for data collected in 2005 and 2006 .Data collected in 2007 was released in October 2010. In-country network operators can release data from their stations to anyone during the three year holding period.

Before archiving data from some stations, it must first be processed for timing corrections and reformatted. Therefore, for some stations, there is a lag between when data are collected and made available at IRIS.
