description: This dataset provides microseism data, produced as part of the ESA Sea State Climate Change Initiative (Sea_State_cci). This microseism dataset is version 1.0, and forms part of the v3 release from the ESA Sea State Climate Change Initiative.Microseism data is a new addition to this CCI Sea State version 3 Dataset. Microseisms are well known to contain rich spectral information about sea states and have been used as early as 1898 to locate typhoons . As such they are unique sources of information on sea states before the advent of surface-following buoys and satellites, with the potential to define long-term trends alongside Voluntary Observing Ship data . Microseisms can be a useful resource when looking for the occurrence of wave events or investigating trends, in particular in regions where no in situ data is available. The data here are spectra of vertical ground displacement at all the available land-based stations from 3 global seismic networks (Geoscope, IRIS USGS and IRIS IDA) from 1988 to 2019. So far microseism data was either handled by seismologists with specific data formats or processed by oceanographers with limited knowledge of the measurement (such as instrument corrections); in the frame of the CCI Sea State project, they have been transformed into yearly NetCDF files containing the seismic spectrograms (Power Spectral Density of displacement) for each station using the âLHZâ channel (vertical displacement sampled at 1 Hz). Note that some of these stations have recordings (with different instruments and stored on different media) that go back to the early part of the 20th century, hence their possible importance for extending climate time series to the pre-satellite era in a future release.
