The NCEDC continues to archive and process electric and magnetic field data acquired from data loggers at two sites (SAO and PKD). At PKD and SAO, 3 components of magnetic field and 2 or 4 components of electric field are digitized and telemetered in real-time along with seismic data to the Berkeley Seismological Laboratory, where they are processed and archived at the NCEDC in a similar fashion to the seismic data (Chapter ).
The system generates continuous data channels at 40 Hz, 1 Hz, and .1 Hz for each component of data. All these data are archived and remain available online at the NCEDC. Using programs developed by Dr. Martin Fullerkrug at the Stanford University STAR Laboratory (now at the Institute for Meteorology and Geophysics at the Univerity of Frankfurt), the NCEDC is computing and archiving magnetic activity and Schumann resonance analysis using the 40 Hz data from this dataset. The magnetic activity and Schumann resonance data can be accessed from the Web.
In collaboration with Dr. Simon Klemperer at Stanford University and Dr. Darcy McPhee at the USGS, the NCEDC is archiving similar continuous electric and magnetic field data from instruments co-located at the Stanford JRSC seismic station.
The NCEDC also archives data from a low-frequency, long-baseline electric field project operated by Dr. Steve Park of UC Riverside at site PKD2. These data are acquired and archived in an identical manner to the other electric field data at the NCEDC.
