Sentences with phrase «global field reconstruction»

The disadvantages of archeomagnetic data for global field reconstruction are their scattered distribution in time and space and their extremely sparse coverage of the southern hemisphere (Fig. 1).

The global field reconstructions of the CALSxk series (Continuous models based on Archeomagnetic and Lake Sediment data spanning the past x kyrs) are regularised spherical harmonic models.

This is likely a consequence of the iterative re-scaling of the relative intensity records of different length and indicates that further investigations on quality and optimal scaling of relative intensity records are necessary to improve global field reconstructions.

Not exact matches

Note that regional proxies, such as the oxygen - isotope temperature reconstructions from the Greenland Ice Core Project that record Dansgaard - Oeschger events, often indicate faster regional rates of climate change than the overall global average for glacial - interglacial transitions, just as today warming is more pronounced in Arctic regions than in equatorial regions (Barnosky et al., 2003; Diffenbaugh and Field, 2013).

A number of new millennial - scale geomagnetic field reconstructions have been published over the last years, based on improved global archeo - and paleomagnetic data compilations.
