    Systematic analysis of magnetic observatory data—I. A proposed method (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 126 (1996), S. 0 
    Details
    ISSN: 1365-246X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: With a view to encouraging magnetic observatory staff to make fuller use of their own data, a simple but rigorous method is presented for the determination of coherent, periodic variations from long series of observatory data. The method is readily adaptable to the different types of data published by observatories, is able to cope with gaps in data, is tuneable to any desired frequency and can run on a modest PC. As an illustration of the method, it has been applied to data from the Kandilli Observatory.

    Annual variation of the geomagnetic field (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 124 (1996), S. 0 
    Details
    ISSN: 1365-246X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: The annual variation of the geomagnetic field is a phenomenon resulting from the movement of the mean latitude of the ring current between summer and winter and is of importance for the determination of deep-mantle conductivity. However, if the annual term is determined from data based on all-day means, it is found to include terms arising from the seasonal variation and modulation of Sq. This effect is investigated both theoretically and experimentally, and it is concluded that the annual variation is best determined from night-time data.

    Notes: [Auszug] ON June 1st, 1831, Commander James Clark Ross "fixed the British flag on the spot, and took possession of the North Magnetic Pole and its adjoining territory, in the name of Great Britain and King William the Fourth"1. The spot referred to was at 70 5?7" N,96 46'45"W where the mean value of ...

    Notes: [Auszug] Jupiter is the largest known planet. It has a mean radius rs of 6.97 x 107 m, more than 10 times that of the Earth, and a mean density of 1,330 kgm"3, close to that of the Sun and about a quarter of that of the Earth. At about 5 x IO12 Pa (50 Mbar), Jupiter's central pressure is more than 10 times ...

    Notes: [Auszug] ON 26 May 1832, the horizontal component of the Earth's magnetic field at Gottingen was 1.7820 mg^mnv^s-1 (=17,820 nT). Not particularly remarkable, you might think, except that this was the first ever absolute measurement of the geomagnetic field and its attainment had required much of the armoury ...

    Notes: [Auszug] To a first approximation (and an extremely good one) the Earth's magnetic field can be represented by that of a uniformly magnetised sphere-the so-called 'centred dipole' model. The orientation of the dipole axis (78.7N, 289.5E) and its motion (0.00 yr-1 N,-0.06 yr"1 E) follow closely the trends ...
