January 19, 2004The NCEDC has extented its continuous archive of 250 Hz data from the HRSN (BP) network with an additional 109 days of continuous 250 Hz data. Continuous 250 Hz data from 2002.228,20:00 - 2002.336,20:00 now available from the HRSN (BP) network in addition to the event-triggered 250 Hz data archive.
The HRSN normally archive continuous 20 Hz data (channels BP1, BP2, and BP3) and low frequency state-of-health (SOH) channels from the HRSN network in addition to the event-triggered 250 Hz data channels DP1, DP2, and DP3. However, continuously recorded DP1, DP2, and DP3 data channels are now available for days 2002.229,20:00 through 2002.337,20:00.
Due to telemetry problems, the 250 Hz channels for some stations and days is highly fragmented. The following table shows, for various timespans, the number of discrete time segments in the raw data that are greater than that timespan. In order to reduce the number of extremely small time segments for normal users of these data channels, the NCEDC removed any discrete timeseries segment that was less than 20 seconds in duration in its normal archive and database descriptor tables.
The full timeseries for these days, however, are available on request from the NCEDC.
