Development of an improved geomagnetic reference field of Antarctica
Geomagnetic reference field spherical cap harmonics polar regions
2015/10/8
The properties of the Earth's core magnetic field and its secular variation are poorly known for the Antarctic. The increasing availability of magnetic observations from airborne and satellite surveys...
A geomagnetic reference model for Albania, Southern Italy and the Ionian Sea from 1990 to 2005
regional main field modelling sphericalcap harmonic analysis magnetic repeat stations
2015/9/15
Taking advantage of the measurements undertaken during the Albanian and Italian magnetic repeat station networks since 1990, as well as of a selected set of 豶sted satellite total field measurements, a...
Comparison of the reference mark azimuth determination methods
Geodetic (ellipsoidal) azimuth Astronomic azimuth Repeat station Reference mark GNSS CROPOS
2015/8/26
The knowledge of the azimuth of the reference mark is of crucial importance in the determination of the declination which is defined as the ellipsoidal (geodetic) azimuth of the geomagnetic meridian. ...
Italian Magnetic Network and magnetic reference fields at 2010.0
Earth's magnetic field Geomagnetic map Magnetic surveys Magnetic repeat stations Secular variation
2015/8/26
The Istituto Nazionale di Geofisica e Vulcanologia (INGV) has systematically undertaken the task of making measurements of the Earth's magnetic field in Italy. By tradition and because of the elongate...
Nonlinear instability of baroclinic atmosphere with reference to planetary scale disturbances
Nonlinear instability baroclinic atmosphere planetary scale disturbances
2009/11/11
In this paper we investigate the stability of zonal flow in a baroclinic atmosphere with respect to finite-amplitude planetary-scale disturbances by applying Arnold's method. Specifically, we examine ...

Climatic Changes in Northern Europe Since Late Glacial Times with special reference to dendroclimatological studies in northern Finnish Lapland.
Oxygen three-isotope ratios of silicate reference materials determined by direct comparison with VSMOW-oxygen
oxygen three-isotope ratios silicate reference materials VSMOW-SLAP normalization terrestrial fractionation line BrF5 fluorination
2017/8/10
The δ17O and δ18O values of some international silicate reference materials such as NBS-28 quartz, NBS-30 biotite, UWG2 garnet, San Carlos olivine and some mineral separates of terrestrial origin were...
The SCEC Southern California Reference Three-Dimensional Seismic Velocity Model Version 2
SCEC Southern California Reference Three-Dimensional Seismic Velocity Model
2014/4/10
We describe Version 2 of the three-dimensional (3D) seismic velocity model of southern California developed by the Southern California Earthquake Center and designed to serve as a reference model for ...
