Geomagnetic main field modeling with DMSP
The Defense Meteorological Satellite Program (DMSP) launches and maintains a network of satellites to monitor the meteorological, oceanographic, and solar-terrestrial physics environments. In the past decade, geomagnetic field modelers have focused much attention on magnetic measurements from missions such as CHAMP, Ørsted, and SAC-C. With the completion of the CHAMP mission in 2010, there has ...
متن کاملChaos in Self-exciting Dynamos and the Main Geomagnetic Field
Nonlinear feedback and coupling (F&C) in dynamical systems operating under fixed boundary conditions usually produce chaotic fluctuations, which are disorderly and unpredictable beyond a finite ‘predictability horizon’ ([(Note) A], [(References) 1-5]). But in some circumstances nonlinear F&C inhibit chaos, producing order rather than disorder. Both types of behaviour may have to be invoked in t...
متن کاملPredicting the Multifractal Geomagnetic Field
The geomagnetic field at the Earth’s surface is determined by a large number of current sources, internal and external, which vary at overlapping time scales. As a result, the time variation of the field, ranging from nHz to tens of Hz, can be modeled as a multifractal whose properties depend on frequency and activity level, with the latter being largely determined by the external driving due t...
متن کاملGeomagnetic field behavior during the Iceland Basin and Laschamp geomagnetic excursions: A simple transitional field geometry?
[1] We present four new records of the Iceland Basin Excursion (IBE) and five new records of the Laschamp Excursion (LE) obtained from rapidly deposited marine sediments in the North Atlantic Ocean, the Nordic Seas, the Gulf of Mexico, the South China Sea, and the southern Indian Ocean. Marked minima in relative paleointensity correspond with the paleomagnetic directional changes associated wit...
متن کاملOn the Geomagnetic Lunar Daily Variation Field
The geomagnetic lunax daily variation field, L, was studied using all available results of lunar analysis of geomagnetic data from a total of 37 stations. Equivalent external (overhead) and internal (induced within the earth) electric current systems responsible for L variations with respect to dip latitude were estimated by the method of spherical harmonic analysis for each season. The externa...
