Kaguya Lunar Multiband Imager (MI) Derived Weighted Criteria Value 50N50S (512ppd) 59mpp

This mosaic represents the weighted criteria values associated with a collection of near-global lunar mineral maps produced by Lemelin et al using data from the Kaguya Multiband Imager (MI). The weighted criteria value provides a measure of the amount of agreement between the reflectance spectrum of a given pixel and the closest matching spectrum from a library of 92,414 synthetic spectral mixtures. To determine the winning composition between multiple spectral library entries, each MI spectrum was compared to the library spectra that have within +/- 2 wt.% FeO of that pixel and the weighted criteria for each corresponding spectral library entry was calculated as follows: (1-correlation) + (absolute difference of continuum removed reflectance).

The winning composition was assigned to the lowest weighted criteria value. Thus smaller weighted criteria values correspond to closer matches between the observed spectrum and the library spectrum.

The mosaic was created from topographically-corrected MI reflectance data acquired by the JAXA SELENE/Kaguya mission (see Ohtake et al., 2013) from the Kaguya Archive MI MAP processing level version 2 (MI MAP_02) products. The MI collects images of the lunar surface at 5 wavelengths in the ultraviolet-visible (UVVIS; 415, 750, 900, 950, 1001 nm) region of the electromagnetic spectrum and at 4 wavelengths in the near-infrared region (NIR; 1000, 1050, 1100, 1250 nm). These multispectral images have been used to derive 9 new near-global maps of the four common lunar minerals, FeO, optical maturity (OMAT), the abundance of SMFe, the grain size for plagioclase, and an estimation of the modeling error using Hapke’s radiative transfer equations (Lemelin et al., 2015; 2016; 2019). These products only cover the latitudinal range +/-50 degrees due to the difficulty of applying adequate corrections for topographic shading at higher latitudes. Preparation details and information on limitations of these products will be presented in a future publication.

The mosaic presented here has been resampled to 512 ppd (59 meters/pixel) from its original resolution of 2048 ppd (15 meters/pixel).

General

Purpose: The SELENE (KAGUYA) mission addressed the origin and evolution of the Moon by obtaining global element and mineral compositions, topological structure, gravity field and electromagnetic and particle environment of the Moon. The MI was a high-resolution multiband imaging camera with a spatial resolution in visible bands of 20 mpp and a spatial resolution in near-infrared bands of 62 mpp from the 100 km SELENE (KAGUYA) orbit altitude. These data support the derivation of many new products, including mineral and elemental abundance maps such as those presented here.

Data Status and Quality

Logical Consistency Report: The MI reflectance data were provided by the SELENE team; information about the MAP processing level reflectance can be found in KAGUYA (SELENE) Product Format Description – Lunar Imager/Spectrometer (LISM (TC/MI/SP)) / SPICE Kernel, version 1.3 (2010). See Source Online Linkage below. The MI ultraviolet-visible (UVVIS) data (5 spectral bands, at 415, 750, 900, 950, 1001 nm) were used to derive 9 new near-global maps of common lunar minerals, FeO, TiO2, and optical maturity (OMAT) using Hapke’s radiative transfer equations (Lemelin et al., 2016).
Completeness Report: The MAP level reflectance data product has been derived from 50N to 50S latitude of the Moon. There are data gaps within the mosaic set to NoData.
