在GPM时代，我们开发了综合GPM模拟器，该模拟器集成了原位观测、CSRM和卫星模拟器，以协同支持GPM降水算法的开发。首先，通过各种野外活动的现场观测对csrm模拟的降水系统进行评估和约束。其次，通过统一的卫星模拟器，从csrm模拟的地球物理参数模拟gpm观测信号（图1）。通过这种方式，采用自下而上的方法将原位点测量“升级”到CSRM尺度（1公里），然后到传感器足迹尺度（5-30公里），最后到卫星带状尺度（125 - 1500公里）。
GPM era, we developed the synthetic GPM simulator that integrates in situ observations, a CSRM, and satellite simulators to synergistically support development of the GPM precipitation algorithms. First, CSRM-simulated precipitation systems are evaluated and constrained by the in situ observations from various field campaigns. Second, GPM-observable signals are simulated from the CSRM-simulated geophysical parameters through the unified satellite simulators (Fig. 1). In this way, a bottom-up approach is taken to “upscale” in situ point measurements to CSRM scales (1 km), then to the sensor footprint scales (5–30 km), and finally to the satellite swath scales (125–1,500 km).
