Simulating desorption in vacuum from a porous soil

This dataset contains simulated data of desorption events from a Monte Carlo simulation of desorption and diffusion in 3D sphere packings. The packings were produced sampling the grain size distribution from Apollo soil 72141.<br> The gas species in these simulations have microphysical parameters consistent with alkali gases (Na, K).<br> The output may enable better representations of the desorption process in global exosphere models of Mercury and the Moon for these species.<br> Output in CSV format is presented as fraction of desorbed test particles versus time.本数据集包含针对三维球堆积体系脱附与扩散过程的蒙特卡洛模拟（Monte Carlo simulation）所生成的脱附事件模拟数据。该球堆积体系通过采样阿波罗（Apollo）72141号土壤的粒度分布构建而成。 本次模拟所涉及的气体物种的微观物理参数与碱金属气体（钠Na、钾K）相符。 本数据集的输出结果可助力优化水星与月球全球外逸层模型中针对上述气体物种的脱附过程表征。 输出采用逗号分隔值（CSV）格式，以脱附测试粒子占比随时间变化的形式呈现。
