Ariel模拟观测公共数据集
收藏资源简介:
该数据集由欧洲航天局Ariel系外行星大气探测任务团队联合开发,基于ExoSim2和TauREx3仿真工具构建,包含约1000个系外行星系统的模拟观测数据。数据集涵盖0.6-3.9μm波长范围内的时序光谱立方体,整合了JWST校准数据衍生的噪声模型及真实光学像差特征。通过耦合大气正向模型与仪器响应函数,该资源为开发去噪算法提供了已知真实值的基准测试平台,主要应用于系外行星大气成分反演和机器学习去噪方法验证,助力未来大规模系外行星普查任务的数据处理挑战。
This dataset was co-developed by the team of the European Space Agency (ESA) Ariel Exoplanet Atmospheric Exploration Mission, and constructed using the ExoSim2 and TauREx3 simulation tools. It contains simulated observational data for approximately 1000 exoplanetary systems. The dataset includes time-series spectral cubes spanning the 0.6–3.9 μm wavelength range, and integrates noise models derived from JWST calibration data as well as real optical aberration characteristics. By coupling atmospheric forward models with instrument response functions, this resource provides a benchmark test platform with known ground-truth values for the development of denoising algorithms. It is primarily applied to exoplanet atmospheric composition retrieval and the validation of machine learning-based denoising methods, and supports addressing data processing challenges for future large-scale exoplanet survey missions.
