Abstract
A series of KMS high resolution near global gravity fields from altimetry have been released during the past 7 years. This presentation focuses on describing the improvements leading to the release of the new KMS2002 field.
Significant improvements have been achieved through careful fine-tuning of the procedure and parameters used for the derivation of gravity from satellite altimetry.
Particularly emphasis has been made in improving the gravity field determination at medium wavelengths ranging between 100–500 km, and at shorter wavelength in coastal regions. Emphasis was made in recovering the gravity field in lakes, which have normally been deleted from global marine gravity field maps. Extensive comparisons carried out at the National Imagery and mapping Agency is also presented to document the improvements made.
