A new technique for continuation of the ground magnetic field caused by ionospheric
currents to the ionosphere in spherical geometry is presented that makes use of elementary …

Many geological features of the Earth's lithosphere create variations in the Earth's magnetic
field that can be detected by satellites. The resulting magnetic anomaly maps can provide …

There is the need for robust alternatives to the widely used spherical harmonic analysis
when measurements are restricted to a region, or when high spatial frequency fields with …

We report new GALLEX solar neutrino results from 15 runs covering 406 days (live time)
within the exposure period 19 August 1992–13 October 1993 (“GALLEX II”). With counting …

We recently proposed a technique able to represent the spatial variations of the magnetic
field at regional scales. However, we pointed out that these preliminary developments were …

地磁测量和地磁场建模是地磁学研究和应用的重要内容之一, 构建全球和局部地区地磁场模型的
物理依据是位场理论, 观测依据是地面, 海洋, 航空, 气球和卫星的磁场探测资料 …

Spherical Harmonic Analysis (SHA) is normally used to model the three‐dimensional global
geomagnetic field. To address the same problem in regional modelling, Haines (1985) …

Spherical cap harmonic analysis has become a well-known technique for regional
modelling of fields that can be expressed as the gradient of a scalar potential, such as for …

Spherical cap harmonic analysis is the appropriate analytical technique for modelling
Laplacian potential and the corresponding field components over a spherical cap. This …

CHAMP satellite data and ground-based magnetic observations are used and combined to
map the lithospheric magnetic field over China by means of the revised spherical cap …
