Description:
We report here on the relationship between titanium abundance and its spectral features on the Moon, using 36 craters exposed in Sinus Iridum, a landing site for China's Lunar Exploration Program. Six absorption parameters (Full Wave at Half Maximum (FWHM), absorption depth (D), absorption position (λ), absorption area (A), absorption asymmetry (S) and (R min ) at the wavelength of 500-550 nm were computed, and the lowest reflectance values (R min ) to characterize the properties of titanium abundance and its spectral features were calculated. The correlation between R min and TiO 2 abundance calculated by Clementine multispectral images is 0.812, and a second-order polynomial fits the data better with a correlation of 0.837. The TiO 2 abundance inversed by the CE-1 IIM data is thus relatively higher than that revealed by the Clementine data. This good correlation between R min and TiO 2 abundance may thus be used very effectively to estimate the Ti distribution on the surface of the Moon by IIM hyper-spectral data.
