Lunar Prospector Spherical Harmonics and Gravity Models

February 2, 2021. Lunar Prospector spherical harmonics data have been migrated to the PDS4 standard.

These archives contain Lunar Prospector spherical harmonic models of the lunar gravity field, digital maps of Bouguer anomalies, free-air gravity accelerations and errors, and geoid anomalies and errors. They also contain documentation that describes the products.

Click on the links to view files and directories in the data sets. See below to download the data sets with FTP.
