Data Center: IESDMC

In mid-1992, along with several domestic and foreign institutions, began to prepare a prospectus for establishing a broadband seismic network in the Taiwan region. The network, later named "Broadband Array in Taiwan for Seismology (BATS)," is initially designed with 15 permanent stations located on Taiwan and the surrounding islands, covering an area of approximately 350 km by 400 km. Currently the number of permanent broadband stations operated by IES is 35, including 2 located in the South China Sea with satellite transmission.

The BATS instrumentation is designed to cover a variety of research demands. All permanent stations are equipped with state-of-the-art very-broadband and strong-motion sensors and 24/26-bits digital recorders. Data streams with high sampling rates (100 sps) were recorded in triggering mode before Q330 was used. After 2002, we gradually upgrade the dataloggers to gain the ability to continuously record ground motion at high sample rates. All stations are capable of internet connection for immediate retrieval of real-time data. We fully take advantage of the Antelope software platform to operate the BATS data acquisition in the data center since 2007. Preliminary data quality control is performed at IES. Afterwards, the data are distributed to the public through the web-based data service at the official BATS website.

We have setup the IES Data Management Center (DMC-IES) which is taking care of the routine network operation, data processing, quality control, and data release, exchange, and contribution etc. The whole dataset is accessible at http://tecws1.earth.sinica.edu.tw/BATSWS in addition to the FDSN Web Service.
