摘要
辐射传输仿真计算由基金项目《风云卫星载荷反射波段在轨精细化定标模型研究》提出,通过计算可以仿真出高精度辐射数据。在实际研究中,由于需要大规模地对气象卫星数据进行仿真计算,发现单一节点计算下存在无法快速地批量完成计算任务的问题。笔者将通过介绍辐射传输仿真计算的数据和流程,并且通过数据和流程的特性结合并行计算的方法分析适合辐射传输仿真计算的并行方案。
The radiation transmission simulation calculation is put forward by the fund project“On-orbit elaborated calibration model for reflective solar bands of Fengyun satellite”.High precision radiation data can be simulated by calculation.In practical research,due to the need for large-scale simulation of meteorological satellite data,it is found that the problem can not be completed quickly in a single node.In this paper,it will introduce the data and process of radiation transmission simulation.Through the analysis of the characteristics of data and flow,the parallel scheme for the simulation of radiation transfer simulation is analyzed.
