摘要：
Precipitation data measured by rain gauges are important in validating estimates from satellite data and model simulation. Gridded precipitation products based on rain-gauge data improve the accuracy of forecasts. However, it is not widely understood that quality control is important in developing a rain-gauge-based precipitation product. In this study, we present examples of abnormal precipitation data for South Asia found in the work of the Asian Precipitation-Highly Resolved Observational Data Integration Towards Evaluation of the Water Resources (APHRODITE) project. We also discuss the use of satellite-based estimates in the quality control of rain-gauge records.
