15th International Congress of the Brazilian Geophysical Society & EXPOGEF, Rio de Janeiro, Brazil, 31 July-3 August 2017. Five arc-minute resolution global ocean depth and land surface elevation. Inverse methods for modeling non-rigid plate kinematics: Application to mesozoic plate reconstructions of the Central Atlantic. Lateral extrusion of the northern Tibetan Plateau interpreted from seismic images, potential field data, and structural analysis of the eastern Kunlun fault. This threshold eliminated about 3% of the marine track line data and 9% of the Project Magnet data. On the origin of the Amerasia Basin and the High Arctic Large Igneous Province—Results of new aeromagnetic data. A preliminary investigation for the assessment of geothermal potential at Eastern Peninsular India. A problem in the line leveling is exposed for the Cayman trough, where the track line data of an entire area were rejected because they exceeded the rms threshold. It will enhance any encyclopedic page you visit with the magic of the WIKI 2 technology. Modelling the Earth’s Magnetic Field from Global to Regional Scales. Long wavelengths in grid and track line data are known to be highly inaccurate. Observed correlation functions, computed from arbitrary rectangular areas in the NGDC magnetic grid of the former Soviet Union and the Australian and the North American magnetic anomaly grids. That's it. This removed about 1% of the segments.

An example of the effect of line leveling and the final merge is shown in Figure 2. This validates our final processing step of merging the short‐wavelength part of the near‐surface data with long‐wavelength satellite magnetic anomalies. Posts about National Geophysical Data Center written by Colltales. This call for data has been encouragingly successful, with good coverage of near‐surface data now available for the first version of the WDMAM, to be unveiled at the International Union for Geophysics and Geodesy (IUGG) General Assembly in Perugia, Italy, in July 2007.

Stitching together surveys and tracks collected at different times only allows for very limited control of wavelengths exceeding typical survey sizes of a few hundred kilometers. The prime candidate for a lack of power in MF5 is the removal of genuine field in the rigorous processing of the satellite data, while excess power in the near‐surface data at 400 km wavelength could be due to spurious large‐scale features introduced in the stitching together of small‐area surveys. Here, we used the lithospheric field model MF5 [Maus et al., 2007], estimated from the latest three years of CHAMP data from August 2003 through July 2006.
