VNIR and MIR spectra of olivine uderwent different degrees of simulated space weathering

Two different energy levels for the pulse have been used, i.e. 25 mJ/pulse and 50 mJ/pulse. Reflflectance measurements from 0.5 to 25 µm and radiative transfer calculations were carried out in order to compare them with each other.

Detailed lab setting and sample information can be found in Yang et al., (2017). There are two datasets, one is the visible and near-infrared (VNIR) spectra data with a wavelength range of 0.5-2.8 μm, and the other one is the mid-infrared (MIR) spectra data with a wavelength range of 1.3-27 μm. There are seven spectra in each of the datasets, includes: unirradiated, 25mJ_1time, 25mJ_2time, 25mJ_3time, 25mJ_4time, 25mJ_5time, 50mJ_2time, and 50mJ_5time. "Unirradiated" represents the spectrum of the original olivine sample, and 25mJ_1time represents the spectrum of olivine irradiated with a pulse energy of 25 mJ for 1 time, and so on.
