The following files are available from cddis.gsfc.nasa.gov: in the directory pub/egm96.

- Information of a general nature is placed in the directory pub/egm96/general_info.
- The surface gravity data is located in the directory pub/egm96/gravity/data .
- The gravity field covariance of EGM96 to Degree and Order 70
is available from cddis.gsfc.nasa.gov and is located in the directory pub/egm96/egm96.covariance.

CAVEAT EMPTOR!!! The covariance is quite large (104 MB compressed).

A geographical grid of the geoid error (to 70x70), and a GIF file are also available. Click on the list below to download these files.
