基于多层次并行的风云三号气象卫星数据定标

The Calibration of FY-3 Satellite Sata Based on Multi-level Parallel

针对风云三号新一代极轨气象卫星遥感数据定标处理,提出了基于.NET框架使用多层次并行计算的方式对遥感数据定标处理进行加速的方案.以可见光红外扫描辐射计所得的遥感数据为测试数据,通过多层次并行计算的方式,进行了可见光近红外通道定标与红外通道定标的快速处理.最后,通过与串行实现、IDL实现的定标处理作对比,证明了.NET框架下多层次并行计算的方式具有一定的优势,所提方案具有可行性.

To address the calibration of the remote sensing data gained by new generation of polar-orbiting meteorological satellite FY-3, the strategy of using multi-level parallel computing based on the. net framework to accelerate the calibration is introduced. Through the multi-level parallel computing, process the near infrared channel calibration and infrared channel calibration for the remote sensing data gained by Visible and Infrared scan radiometer （VIRR）. Finally, it proves that the proposed strategy is feasible by comparing the multi-level parallel computing based on the. NET framework to the serial computing and IDL.
