Geomagnetism : review 2010
The Geomagnetism team measures, records, models and interprets
variations in the Earth’s natural magnetic fields, across the world
and over time. Our data and expertise help to develop scientific
understanding of the evolution of the solid Earth and it’s
atmospheric, oceanic and space environments. We also provide
geomagnetic products and services to industry and academics and
we use our knowledge to inform and educate the public, government
and the private sector
An investigation into techniques for isolating noise in observatory data
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 individual observatory. With the aim of developing an analytical tool
that can be used to identify observatory noise against the natural signal, we report on the suitability of these
techniques to detect common observatory noise types
