摘要

CRTM透射系数生成包是为JCSDA群落辐射传输模型（CRTM）生成光谱和透射系数的高性能计算工作流程，该模型在卫星数据同化应用中用作观测算子。新仪器的观测结果由CRTM建模，其特征被封装在上述系数数据结构中。这种方法是实现CRTM所需的高计算速度的关键因素。特别是用ODPS和ODAS算法来近似复杂的大气透射光谱。透光系数生成包首次为CRTM生成系数提供了一个统一的、可重复的工作流程。

The CRTM transmittance coefficient package

The CRTM transmittance coefficient generation package is a high-performance computing workflow to generate spectral and transmittance coefficients for the JCSDA Community Radiative Transfer Model (CRTM), which is used as an observation operator in satellite data assimilation applications. The characteristics of new instruments, whose observations are modeled by the CRTM, are encapsulated in these aforementioned coefficient data structures. This approach is a key factor in achieving the necessary high computational speeds with the CRTM. Complex atmospheric transmittance spectra in particular are approximated using the ODPS and ODAS algorithms. The transmittance coefficient generation package for the first time provides a unified and reproducible workflow to CRTM generate coefficients.
