A Method for Combined Satellite and Rain Gauge of Precipitation over Qinghai

The spatial and temporal distribution of precipitation is needed for a variety of scientific research, obtained usually used two ways, one is rain gauges measurement for using interpolation, another is remote sensing data which retrieval from satellite. But satellite estimates are indirect and need to be calibrated or verified using the gauge observations. In this paper, one method which based on combination of rain gauge and satellite is used to get the distribution of precipitation over Qinghai. Cross-validation tests is carried out to validate the approach. The results show that the method is suitable to produce high-resolution of precipitation over plateau.
