AB: Seismic Array Laboratory (SAL, IGGCAS) was built up in 2000, whose initiative was to study the earth structures through portable seismic observation and it has been operating for about 7 years till now. Totally, the lab have 272 sets of seismographs, including 152 CMG-3ESP seismometers, 18 CMG-3T seismometers, 2 STS-2 seismometers, 100 domestic seismometers, 172 Reftek recording system and 100 domestic recording system, respectively. The seismographs in IGGCAS are only used for temporary seismic observations and are open to users who aim at seismic observation based research and, in principle, are able to afford instrument rental. For the past seven years, more than 10 scientific research groups have used these seismographs and set up more than 470 portable stations in Chinese mainland. Up to now, IGGCAS has carried out 15 temporary seismic station arrays which are mainly distributed in North and Southwest China. The data collected at these seismic stations are currently managed by the SAL of IGGCAS and some regulations have been set down for data usage. Users who implement seismic observations with the seismographs in IGGCAS have three years priority to use the corresponding seismic data after field operation. Then, those data should be released by the SAL of IGGCAS. Now, parts of the data have been open to public through the website http://www.seislab.cn/data, and currently, only some event data in SAC format are released due to the lack of high-level technicians dealing with data pre- processing and quality control. In the near future, the lab will release more data in multiple formats to facilitate researchers in relative area via internet connection.
