| Abstract: | China Digital Seismograph Network (CDSN) has bee operated since October of 1986by the full cooperation between China State Seismological Bureau (SSB) and UnitedStates Geology Survey (USGS). Three component data of four kinds of various frequency band, short period (SP), broad band (BB), long period (LP) and very long period(VLP), are recorded. The digital VLP seismological waveform data are recorded in network-month tape in CDSN. The network-month tape includes its month log file, stationmonth log file and VLP data file, where data month log and VLP data are included inVLP data file. The physical structure in network-month tape is non-structured dataflow, in which one physical block has 2000 bytes and one file is composed of blocks.There are three kinds of record types in network-month tape, which are ASCII codeand binary data, respectively. |
