Sentence examples for to champ data from inspiring English sources

However, the misfit to the other two vector field components (B ⊥ and B 3) was approximately 0.5 nT lower for Swarm data compared to CHAMP data (note the distinction between B ⊥ and B 3 is arbitrary for Swarm, while CHAMP data with either one or two star cameras operating have been considered).

In the lower frame of Fig. 4 the GRIMM versions differ by the estimation window length in days (w =99, 10, 20); the r2 in the label indicates an additional data filtering applied to CHAMP data to reduce outliers.

An instructive test case was the application of a DCO predecessor to CHAMP data, but here only a comparison with Euler angle estimations provided by other modelers can be presented.

The SIFMplus model provides a description of the static lithospheric field that is very similar to models determined from CHAMP data, up to at least spherical harmonic degree (n=75).

(2012) used CHAMP data to develop a global model of Birkeland currents using empirical orthogonal functions.

However, spacecraft recordings of sufficient length give a reliable average description, as shown by Juusola et al. (2009), who studied five years of CHAMP data to determine auroral ionospheric currents (altitude adjusted corrected geomagnetic latitudes 55 76.5 deg).

The global field, which shields the planet from high-energy particles emanating from the Sun, appears to be getting weaker, particularly over the South Atlantic where Champ data was used to show there had been a 12% reduction during the course of three decades.

For this assessment, all CHAMP data belonging to the selected time interval were considered, not only those decimated on the quasi-regular grid.

The SIFMplus model provides a description of the static lithospheric field that is very similar to that of the MF7 (Maus 2010) and CHAOS-6 (Finlay et al. 2016) models which were determined from CHAMP data, up to at least spherical harmonic degree (n=75).

In contrast, as the selected CHAMP data were all acquired when both CHAMP star imagers were operating, all CHAMP data were isotropically weighted.

The CHAMP data were downsampled to one measurement every 20 s and additionally corrected for ocean tidal fields (Kuvshinov and Olsen 2005), diamagnetic currents originating in the ionosphere (Lühr et al. 2003), and external magnetospheric fields (Lühr et al. 2010).
