A new geomagnetic observatory network?

Eos, Transactions American Geophysical Union, 1993
Input and comments are solicited for a study of the network of geomagnetic observatories. Although there are some 200 geomagnetic observatories around the world recording the intensity and direction of the geomagnetic field, they were established over the last 2 centuries without any overall plan and do not satisfy many of today's scientific and ...

Anomalous changes of vertical geomagnetic field in Kamchatka

E3S Web of Conferences, 2016
Secular variations of the vertical geomagnetic field at Paratunka (Kamchatka), Kakioka (Honshu), Mamambetsu (Hokkaido) and Patrony (Irkutsk) are considered from 1968 to 2014.

An Investigation into Techniques for Isolating Noise in Observatory Data

Data Science Journal, 2011
In this study, using one-minute definitive data published by a number of INTERMAGNET observatories, we apply a number of time- and frequency-domain techniques to characterise the global, natural geomagnetic signal and isolate the artificial noise at an ...

Availability and Access to Data from Kakioka Magnetic Observatory, Japan

Data Science Journal, 2013
The Japan Meteorological Agency (JMA) is operating four geomagnetic observatories in Japan. Kakioka Magnetic Observatory (KMO), commissioned in 1913, is the oldest. The hourly records at KMO cover over almost 100 years.

Improvements in geomagnetic observatory data quality

, 2011
Geomagnetic observatory practice and instrumentation has evolved significantly over the past 150 years. Evolution continues to be driven by advances in technology and by the need of the data user community for higher-resolution, lower noise data in near ...

Deep-Sea Vector Geomagnetic Observations from a Mooring Platform: Instrument Demonstration and Geophysical Data Quality

Journal of Marine Science and Engineering
Despite their importance for constraining lithospheric magnetization models, tracking secular variation in oceanic regions, and improving global geomagnetic field representations, long-term vector geomagnetic data from deep-sea environments remain scarce.

Plasmaspheric dynamics resulting from the hallowe'en 2003 geomagnetic storms [PDF]

, 2009
Cross-phase-derived plasma mass density trends during the Hallowe'en 2003 geomagnetic storms are presented for 38° magnetic latitude 63° (1.61 ≤ L ≤ 5.10), using data from the SAMNET (Subauroral Magnetometer Network), BGS (British Geological Survey), and
