High Resolution Earth Gravity Field Models from Satellite and Tracking Data, Sea Surface Heights and Gravity Anomalies, Spherical Harmonic Representation
Entry ID: GFZ-High_Res._Earth_Grav_Models


Summary
Abstract:

The high resolution Earth gravity field models, produced by GFZ,

contain spherical harmonic coefficients complete to degree and order



  1. A-priori information is taken from long wavelength gravity field

    GRIM (see other GFZ data set descriptions). High frequency

    determination is based on both surface gravity and ocean geoid

    heights. Surface gravity is ...


    The estimation of the 360 field is based on a least squares harmonic

    analysis.




With globally distributed, equally spaced data sets, the normal

equation system decomposes to block diagonal structure. Undefined data

are successively substituted by block mean values from intermediate

results.
