Below is a list of products currently under development and produced either at the DMC or by the research community that are available from the DMC.
Have a data product idea? Feel free to suggest a data product .
Noise Toolkit PDF-PSD Noise Toolkit PDF/PSD bundle
An open-source script bundle that contains a series of Python scripts to:
- request waveforms and response data for given station/channels using the ObsPy FDSN client
OR read user’s waveform data files (in SAC, MSEED, CSS, etc. format) and only request response information
- compute and populate an hourly file-based PSD database
- extract PSDs and PDFs from the PSD database
Noise Toolkit ME Noise Toolkit Microseism Energy (ME) bundle
An open-source script bundle that contains 3 Python scripts to:
- calculate power from PSDs over selected period bands (bins)
- calculate median power for a given time window from the computed PSD powers
- plot temporal variation of median power
MEQL - typhoon Maysak Microseism Energy Quick Look (MEQL) Highlight - super typhoon Maysak
Images on this page represent the median integrated power time series calculated from the power spectral densities (PSDs) for the vertical, N-S and E-W components of selected seismic stations along the path of super typhoon Maysak (formed on 2015-03-26 & dissipated on 2015-04-07).
MEQL - typhoon Haiyan Microseism Energy Quick Look (MEQL) Highlight - typhoon Haiyan
Images on this page represent the integrated median power time series calculated from the power spectral densities (PSDs) for the vertical, N-S and E-W components of selected seismic stations along the path of typhoon Haiyan (formed on 2013-11-03 & dissipated on 2013-11-11).
MEQL - OBS microseism - Axial Volcano Microseism Energy Quick Look (MEQL) Highlight - ocean-bottom seismic and hydroacoustic data at the secondary microseism band of 0.1-0.35 Hz for the Axial Volcano eruption, 2015-04-24
The underwater Axial volcano (see Figure 1) erupted on April 24, 2015. The OO – Ocean Observatories Initiative network of Ocean-Bottom Seismometer (OBS) stations, equipped with hydrophones sensors, have been deployed in that area since 2014 and provide excellent opportunity to correlate microseism noise variations with changes in water pressure and ocean wave activities due to this eruption. This microseism energy quick look (MEQL) highlight provides a sample of such comparison utilizing seismic and hydroacoustic data from the AXBA1 and HYS14 stations of this network as well as standard meteorological data from the National Data Buoy Center.
