Measurements of Short-Period Magnetic Field Data

Acquisition of short-period magnetic field data at the Pt. Barrow, Alaska, CMDL site was carried out normally throughout 1996-1997. Stable operation of the search coil magnetometer was achieved after a replacement of the data logging unit. Direct communication to the site using E-mail has also helped in quick response time to identify and fix problems.
Data up to 1.8 GB were regularly delivered by FedEx, retrieved, and stored as Unix files. Checking quick-look analysis data, all data are recorded normal. A general tendency over the years of activity of short-period geomagnetic pulsations has declined as the solar activity went into the minimum phase. The data set obtained at the Barrow site has been helpful to watch the state of short-period geomagnetic disturbances at the west-north end of our magnetometer network extending into the polar region of North America. Data requests are responded to through our web page at hpep3.geoph.s.u-tokyo.ac.jp. Some testing analysis will be prepared from the home page. This program is expected to continue until the end of this century.
