CO2标准吸收光谱参数库

本数据集是一个高精度的CO₂分子吸收光谱参数库，旨在为温室气体的高精度遥感监测与模拟提供核心物理基础。数据集系统地收录了CO₂分子在近红外至中红外波段的吸收光谱参数，包括详细的线强、半宽度以及Lorentz、Doppler、Voigt等多种散射线型函数。构建过程基于国际公认的HITRAN2020等权威分子光谱数据库，并针对不同大气温度与压力条件进行了精细化的建模与适配。为确保参数的准确性与可靠性，所有数据均经过严格的理论计算与高精度的光腔衰荡光谱（CRDS）实验测量交叉验证，关键吸收线的筛选敏感阈值达到0.09%。该参数库是开发新一代高光谱温室气体卫星（如我国的碳卫星）反演算法、进行高保真大气辐射传输模拟、以及为地基和空基观测设备提供定标基准的关键工具。数据集以结构化的文本格式组织，可直接应用于科学研究与工程开发，为应对气候变化提供坚实的数据支撑。(协议共享)

This dataset is a high-precision CO₂ molecular absorption spectral parameter library, which aims to provide the core physical foundation for high-precision remote sensing monitoring and simulation of greenhouse gases. It systematically collects CO₂ molecular absorption spectral parameters covering the near-infrared to mid-infrared bands, including detailed line strengths, half-widths, and various broadening line shape functions such as Lorentz, Doppler, and Voigt profiles. Constructed based on authoritative molecular spectral databases such as the internationally recognized HITRAN2020, the dataset has been finely modeled and adapted for different atmospheric temperature and pressure conditions. To ensure the accuracy and reliability of the parameters, all data have undergone cross-validation via rigorous theoretical calculations and high-precision Cavity Ring-Down Spectroscopy (CRDS) experimental measurements, with the screening sensitivity threshold for key absorption lines reaching 0.09%. This parameter library serves as a key tool for developing inversion algorithms for new-generation hyperspectral greenhouse gas satellites (such as China's TanSat), conducting high-fidelity atmospheric radiative transfer simulations, and providing calibration benchmarks for ground-based and space-based observation equipment. Organized in structured text format, the dataset can be directly applied to scientific research and engineering development, providing solid data support for climate change response.
