Localized spectral analysis on the sphere 657

  title={Localized spectral analysis on the sphere 657},
  author={Mark A. Wieczorek and Frederik J. Simons},
S U M M A R Y It is often advantageous to investigate the relationship between two geophysical data sets in the spectral domain by calculating admittance and coherence functions. While there exist powerful Cartesian windowing techniques to estimate spatially localized (cross-)spectral properties, the inherent sphericity of planetary bodies sometimes necessitates an approach based in spherical coordinates. Direct localized spectral estimates on the sphere can be obtained by tapering, or… CONTINUE READING
