Terahertz time-domain spectroscopy data for proton-irradiated Martian silicate analogs

This dataset contains terahertz time-domain spectroscopy (THz-TDS) measurements of the refractive index and absorption coefficient of proton-irradiated Martian silicate analogs, including plagioclase, olivine, and pyroxene. The data provide frequency-resolved terahertz optical properties that form the basis for analyzing irradiation effects and environmental responses relevant to the Martian near-surface environment. The measurements were designed to investigate proton-irradiation–induced modifications of terahertz optical properties and their subsequent environmental modulations under Mars-relevant conditions. After proton irradiation, the samples were characterized over a frequency range of 0.15–1.50 THz while systematically varying temperature from 143 to 293 K and carbon dioxide pressure from 1 to 20 mbar, covering representative thermal and pressure regimes on present-day Mars. All files in this archive contain the values of the refractive index and absorption coefficient. The irradiation-induced modifications and environmental modulations discussed in the associated manuscript are derived from these raw measurements through comparative analyses across irradiation states, temperatures, and pressures. The data are provided in comma-separated values (CSV) format and organized by optical parameter, with separate directories for refractive index and absorption coefficient. Each CSV file corresponds to a specific experimental series, including pressure series at fixed temperature, temperature series at fixed pressure, and frequency-resolved spectra at reference temperatures of 223 K and 293 K. This dataset supports the analyses presented in the associated manuscript submitted to JGR: Planets and is intended to facilitate reproducibility and future comparative studies of terahertz remote sensing signatures and space-weathering processes in Martian regolith analog materials.本数据集收录了质子辐照火星硅酸盐类似物的太赫兹时域光谱（terahertz time-domain spectroscopy, THz-TDS）测量数据，所测样本涵盖斜长石、橄榄石及辉石三类，数据包含其折射率与吸收系数两项参数。该数据集提供了频率分辨式太赫兹光学特性数据，可为分析火星近地表环境相关的辐照效应与环境响应提供核心支撑。 本次测量旨在探究质子辐照诱导的太赫兹光学特性变化，以及火星相关环境条件下该特性的后续环境调控效应。质子辐照完成后，研究团队在0.15~1.50 THz的频率范围内对样本进行表征，同时系统调控温度（143~293 K）与二氧化碳分压（1~20 mbar），覆盖了当前火星典型的热环境与压力环境区间。 本归档文件中的所有数据均包含折射率与吸收系数的数值。相关稿件中提及的辐照诱导特性变化与环境调控效应，均通过对不同辐照状态、温度与压力下的原始测量数据开展对比分析得到。 数据以逗号分隔值（comma-separated values, CSV）格式存储，按光学参数分类归档，分别设置了折射率与吸收系数两个独立目录。每个CSV文件对应一组特定的实验序列，包括固定温度下的压力梯度测量系列、固定压力下的温度梯度测量系列，以及223 K与293 K参考温度下的频率分辨光谱数据。 本数据集可为投稿至《地球物理研究杂志：行星（JGR: Planets）》的相关稿件中的分析内容提供支撑，同时旨在助力研究结果可重复性验证，以及未来针对火星风化层类似物的太赫兹遥感特征与空间风化过程开展对比研究。
