摘要：
The Global Positioning System (GPS) ray-shooting model is a self-sufficient observation operator in GPS/MET (Meteorology) data variational assimilation linking up the GPS observation data and the atmospheric state variables. But its huge computations make it impracticable in real data assimilation so far. In order to overcome this default, a parallel version of the GPS ray-shooting model has been developed, and has been running Successfully on the PC cluster manufactured under the support of the China National Key Development Planning Project for Basic Research: The Large Scale Scientific Computation Research, High speed-Lip and Efficiency as well as good scalability are obtained. This is an important step for this GPS observation operator to become practicable.
