The data set "Lunar Elemental Abundances" contains nearly global maps of the abundances of the elements Fe, Mg, Ca and Ti. These maps were derived from hyperspectral data of the Moon Mineralogy Mapper (M³) instrument on-board the spacecraft Chandrayaan-1 in combination with data of the instruments Lunar Prospector Gamma Ray Spectrometer (LP GRS) and Kaguya Gamma Ray Spectrometer (KGRS). They are provided in GEOTIFF format, their pixel values represent elemental abundances in weight percent, and their resolution is 20 pixels/degree. The maps and the method used for determining the elemental abundances have been introduced in the following publication:
