This is the high-precision Spectral Profiler (SP) data obtained by applying local topographic corrections to the spectral data acquired by KAGUYA’s onboard Spectral Profiler, which is a continuous visible-near infrared spectrometer.

The Kaguya SP dataset covers the entire globe of the Moon with a spectral resolution of several nm, which makes it possible to identify minerals on the surface of the Moon.

This is a preliminary version as of 2022 and may be updated in the future.
In this preliminary release, the SP data corresponding to a part of the south polar region were used for the higher-level processing.

The following datasets are used for reference:

• Solar flux at each wavelength corresponding to each SP band (Yamamoto et al., 2011)
• Photometric correction parameters (Yokota et al., 2011)
• SLDEM2015 (Barker et al., 2016)

These products were prepared by Yoshiko Ogawa (The Univ. of Aizu) and her colleagues. This is a preliminary version as of 2022 and may be updated in the future.

Processed data

The source data are available from DARTS, SP_Level2C Version 03.

A small portion of the data from the south polar region that met the conditions below were processed to a higher order:

• 185-190 E, 65-70 S
• rev# < 5690 (~altitude > 88 km)
• VIS#1-84, NIR1#1-97, total 181 bands
