Siple Experiment VLF Data Quick-look Broadband Summary Charts

2021-03-02 17:39:48Z

The broadband summary chart stitches together the
first second of each hour in the day. For VLF data (100 kHz
sampling), the spectrogram will display from 0.3 kHz to 50
kHz. Note, these are not 24-hour-long spectrograms, but rather only
the first second of each hour (if available) is displayed. This
provides a quick and easy way to evaluate the operation of the
receiver and the noise environment, but more detailed analysis
requires downloading the actual data.

Each chart consists of two plots, the upper plot displays magnetic
field output from the North-South antenna, the lower plot displays
the magnetic field output from the East-West antenna. These are 24
Hour plots. The title of the chart indicates the name of the
station and the year-month-day of the observation.

DATA USAGE POLICY The data in the WALDO database have been collected by Stanford University, the Georgia Institute of Technology, and the University of Colorado Denver. Funding has been provided by the United States government under various basic science research grants over many years. To maximize the benefit of those investments, WALDO data are released without restriction, and can be freely analyzed or published. The curators of WALDO are Morris Cohen (Georgia Tech) and Mark Golkowski (CU-Denver). We request that the following acknowledgement be added in any publication using data from WALDO "VLF data are provided by the WALDO database (https://waldo.world), operated jointly by the Georgia Institute of Technology, and the University of Colorado Denver, using data collected from those institutions as well as Stanford University, and has been supported by various US government grants from the NSF, NASA, and the Department of Defense." If extensive amounts of WALDO data are used in a publication, the curators request, but do not require, to be contacted to discuss the possibility of joint authorship, with the WALDO curators providing help analyzing and interpreting the large dataset.
