NEar-Source Strong-motion flatfile from eBASCO (NESS-eBASCO), version 2.0

Near-source strong-moton flatfile SD (called NESS-Sdebasco) is a parametric table related to world earthquakes containing high-quality metadata and intensity measures (IMs) based on displacement of engineering interest. The table collects 5% damping spectral displacement ordinates and permanent displacement (fling step) along with the corresponding event and station metadata. The accelerometric recordings contained in the table (about 600 near-source three-component waveforms) are processed uniformly according to the eBASCO (Extended Baseline Correction) processing scheme, applied to remove the baseline of recordings by means of a piece-wise linear detrending of the velocity time-histories. Differently from standard processing schemes used to process NESS2 strong-motion data (10.13127/ness.2), eBASCO does not apply any filter that changes the low frequency content of the signal, allowing to determine the velocity pulses and the and the offset at the end of the displacement trace.
