NIPR Lunar Meteorites

Visible and Near-Infrared Spectral Survey of Lunar Meteorite Chips Stored at the National Institute of Polar Research

This is a compilation of photographs and Visible and Near-Infrared (VNIR) reflectance spectral data of lunar meteorites stored at the National Institute of Polar Research (NIPR) measured while Takahiro Hiroi was a visiting professor at NIPR during the summer of 2010.  The project was later funded by the Japanese Government grant (JSPS KAKENHI Grant Number 24540493).  The detailed results were published as:

T. Hiroi, H. Kaiden, A. Yamaguchi, H. Kojima, K. Uemoto, M. Ohtake, T. Arai, S. Sasaki (2016) Visible and near-infrared spectral survey of lunar meteorites stored at the National Institute of Polar Research.  Polar Sci. (Published online on June 10, 2016).
