Data Access

The INSN network code is “EI” and station data can be downloaded via FDSN web services at GFZ FDSNWS  and IRIS FDSNWS.  The most convenient way of downloading, pre-processing and plotting data is provided by the IRIS Timeseries Web Service, see example below.  Please cite any INSN data usage with doi 10.7914/SN/EI.
