Approximate decorrelation and non-isotropic smoothing of time-variable GRACE-type gravity field models
Wediscuss a newmethod for approximately decorrelating andnon-isotropically filtering themonthly gravity fields provided by the gravity recovery and climate experiment (GRACE) twin-satellite mission. The procedure is more efficient than conventional Gaussiantype isotropic filters in reducing stripes and spurious patterns, while retaining the signal magnitudes. One of the problems that users of G...
متن کاملImproved accuracy of GRACE gravity solutions through empirical orthogonal function filtering of spherical harmonics
[1] One of the major problems one has to deal with when working with Gravity Recovery and Climate Experiment (GRACE) data is the increasing error spectrum at higher degrees in the provided Stokes coefficients, appearing as unphysical North-South striping patterns in the maps of equivalent water height (EWH). This phenomenon is commonly suppressed by application of a Gaussian smoothing filter, w...

translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
